You wire packs in parallel (never series) up to sixteen units, and you charge in temperatures above 0°C because there is no self-heating. This guide walks through bracket, clearances, comms matching, grounding, parallel wiring and commissioning for a safe, code-compliant install across Europe.

The charge voltage is 58.4V, not a generic "48V" setting.** The pack works across 43.2–58.4V and must be charged to 58.4V. If your hybrid inverter floats lower, the pack never reaches full; a wrong, higher profile damages the cells. Set the LiFePO4 / 16-cell profile with a 58.4V absorption. **2\. The low cut-off is 43.2V.** When the inverter sees the battery drop toward 43.2V, it should disconnect essential loads — that is the BMS's own lower working bound. Do not set the inverter cut-off below it and hope to squeeze out more. **3\. Communications must match: CAN 500 kbps, RS485 at 9600 baud, RS232 available.** Pick one protocol that your inverter supports and wire it correctly. A parallel bank uses the dual RS485 ports to daisy-chain packs so they coordinate. **4\. The unit weighs 44 kg and is wall-mounted.** It needs a strong wall, the supplied steel bracket and a two-person lift. Expansion bolts into brick or concrete; never into hollow plasterboard alone. **5\. Wire in parallel, up to sixteen packs, never in series.** The pack is already 48V class. Parallel keeps 51.2V and adds capacity; sixteen parallel packs reach 81.92kWh. Series to a higher voltage is not supported. **6\. Indoor, IP54, and no charging below 0°C.** This is an indoor unit — a utility room, garage or boiler room — with IP54 dust-splash protection. It has no self-heating, so do not charge it in a freezing unheated space in winter. ## Step 1 — the wall bracket, clearances and the 44 kg lift Each pack is 640 mm high, 428 mm wide and 160 mm deep, and weighs 44 kg. The supplied steel bracket (about 410 × 322 mm) bolts to the wall with four expansion bolts and wall plugs. Fix it to brick, concrete or a suitably studded timber wall — not to plasterboard or a hollow partition alone. Plan the mounting height so the round LCD and the lower terminal cover are easy to reach, and leave clear space around the unit for ventilation and cabling: keep the sides and top clear of obstructions and route the power and comms cables down and away from the front face. Install parameter Value / guidance Unit size (H × W × D) 640 × 428 × 160 mm Weight 44 kg — two-person lift Bracket Steel, approx. 410 × 322 mm, four expansion bolts Wall type Brick / concrete / studded timber — not bare plasterboard Environment Indoor, IP54, −10 to 50°C operating; humidity <95% RH Clearance Keep sides/top clear for ventilation and cable service Lift the hung unit onto the bracket with a helper, engage the mounting rail, and confirm it is seated and stable before you let go. A 44 kg wall battery that comes loose is a serious safety event — torque the expansion bolts into the wall substrate, not just the plaster skin, and re-check the fixings after the first week. ## Step 2 — set the inverter battery profile to 58.4V The hybrid inverter is a separate device; the battery itself contains no inverter and no mains output. On the inverter's setup menu you tell it what battery it is fed by. Choose the LiFePO4 (LFP) chemistry and the 16-cell / 48V-class profile, then set the numbers that match this pack exactly. Setting on the inverter Value for this pack Chemistry LiFePO4 / LFP (not lead-acid) Absorption / charge voltage 58.4V Working voltage window 43.2–58.4V Low cut-off / disconnect 43.2V Charge / discharge current limit Set to 50A rated (100A short-time max) Depth of discharge 80% recommended (6000-cycle rating) A lead-acid profile that floats lower than 58.4V will under-charge the pack and leave it perpetually short of full. Equally, a profile that pushes past 58.4V will over-charge the cells. Always set the LiFePO4 profile and confirm the absorption voltage reads 58.4V before you energise. Plan the inverter's charge current around the 50A rated figure; the 100A limit is a short-time maximum, not an all-day charge rate. ## Step 3 — match the communications: CAN, RS485 or RS232 Beyond power cables, the battery talks to the inverter over a data wire so the inverter reads state of charge, cell voltage and temperature, and can ask the battery to charge or stop. The pack offers three ports, and you use whichever your hybrid inverter supports. Port Setting Use CAN-BUS 500 kbps Common with many 48V hybrid inverters; plug into the inverter CAN port RS485 9600 baud Widely supported; two RS485 ports let you daisy-chain a parallel bank RS232 Serial For monitoring / setup with a PC or compatible device For a single pack, run one comms lead from the battery to the inverter's matching port and select the corresponding battery model in the inverter menu. For a parallel bank, use the dual RS485 ports to link the packs in a daisy chain so they share data and the inverter sees one coordinated bank. If the inverter has a list of battery brands, pick the one whose CAN/RS485 protocol matches this pack; a mismatched protocol leaves the inverter blind to the battery even though the power cables are correct. ## Step 4 — power cables, fusing and grounding Run the positive and negative DC cables from the lower terminal posts to the hybrid inverter, using ring lugs sized for the terminals and torqued evenly. Fit a DC fuse or circuit breaker close to the positive terminal of the battery bank — it is the device that disconnects a short circuit, not the BMS alone. For a single 50A-rated pack, size the fuse just above the rated charge/discharge current; for a parallel bank, fuse each string and again at the main bus. Ground the installation as your local wiring code requires: connect the protective earth to the battery's grounding point and to the inverter earthing, and bond the wall-mounted metalwork where the installation calls for it. Keep the comms cables routed separately from the thick power cables to avoid interference, and dress the cables neatly into a cable tray or conduit below the unit. Because this is a 48V-class bank the DC current is modest, but short circuits at these energies still demand proper fusing — never energise the bank without the DC breaker fitted. Keep the battery's power switch off until the very end: mount the bracket, bolt the unit, dress and bolt the DC cables, fit the fuse and breaker, run the comms lead, connect the earth, and only then switch on. Wiring with the bank dead is far safer than bolting cables onto a live 51.2V bus. Torque the ring-lug terminals evenly to the figure in the manual, leave no loose strands, and route the cables so nothing presses against the LCD or the terminal cover. ## Step 5 — parallel wiring up to sixteen packs When you add more packs for more kWh, wire them in parallel — positive to positive, negative to negative — on the same 51.2V bus. Do not wire them in series; this battery is already at 48V and a series connection to a higher voltage is not supported. Use identical units, brought to a similar state of charge before connecting, and link their data ports with the dual RS485 daisy chain so they coordinate as one bank. Parallel bank Voltage Stored energy Install note 1 pack 51.2V 5.12kWh Single wall unit, one comms lead 2 packs 51.2V 10.24kWh Side-by-side, parallel power, RS485 daisy-chain 4 packs 51.2V 20.48kWh Wall grid, fused strings 16 packs 51.2V 81.92kWh Maximum parallel bank — installer-designed ![A large parallel battery bank in a tidy utility room, many slim white wall batteries mounted in neat rows and columns across a large wall, neat black power and grey comm cables running along a cable tray below](https://aka.doubaocdn.com/s/UZkBc0iSQ2) A parallel bank of wall units — up to sixteen — shares one 51.2V bus, with the dual RS485 daisy-chain coordinating them as one. Keep cable runs between parallel packs equal in length so current shares evenly, and mount each pack on its own bracket on a wall strong enough for the combined weight. A sixteen-pack bank is a structural and electrical project for a qualified installer — not a weekend DIY job. ## Step 6 — commissioning on the LCD and power switch Once the bracket, power, comms and ground are done, commission the system. Switch the battery on with its power switch and read the round LCD: it shows state of charge, voltage and current. Confirm the pack reads around 51.2V at rest and that the inverter now displays the battery state of charge over the comms link — if it does not, re-check the CAN/RS485 protocol and baud setting before continuing. Run a brief charge and discharge test: start a small load, watch the LCD voltage and current, and verify the inverter responds to the battery. Confirm the 43.2V cut-off and the 58.4V absorption are correctly reflected by charging once from a mid state of charge. Finally, check the fixings, the fuse ratings and the clearances, and log the install date — the pack carries a 10-year design life and is rated for 6000 cycles at 80% depth of discharge, so a correctly commissioned bank will run for many years. ## Temperature and placement: IP54 indoor, no self-heating The pack is IP54 rated for indoor use in a utility room, garage or boiler room — it is not a fully outdoor unit and should not be exposed to rain or standing water. It operates between −10°C and 50°C and stores between 0°C and 35°C, but it **must not be charged below 0°C**, and it has no built-in self-heating element. In a cold European winter, install it in a heated or frost-protected space; if the room can freeze, bring the battery above freezing before charging. This is the most common avoidable fault — charging a lithium pack in a freezing unheated garage — and it is why placement matters as much as wiring. ## Final verdict — a safe, code-compliant install Wall-mount the GSIKE FixWall on a properly fixed steel bracket, set the hybrid inverter to the 58.4V LiFePO4 profile with a 43.2V cut-off, connect the matching CAN (500 kbps) or RS485 (9600) comms lead, fuse and ground the DC feeds, parallel identical packs up to sixteen on the 51.2V bus, and commission on the round LCD and power switch. Keep it indoors at IP54, protect it from freezing for charging, and leave the structural and comms design of a large parallel bank to a qualified installer. Done this way, one 5.12kWh pack — or a sixteen-pack 81.92kWh wall — is a decade-plus asset. ## The Bottom Line — set 58.4V, match the comms, and bolt it to a real wall Three things decide whether this install works: the inverter profile must say 58.4V charge and 43.2V cut-off, the CAN or RS485 comms must match the inverter's battery protocol, and the 44 kg pack must hang on expansion bolts in a real wall with a helper. Wire packs in parallel up to sixteen, never in series, commission on the LCD, fuse and ground every feed, and keep the unit indoors above freezing — there is no self-heating to rescue a cold garage. ## Frequently asked questions What charge voltage should I set my hybrid inverter to for this battery? Set the LiFePO4 / LFP profile with an absorption charge voltage of 58.4V. The pack works across 43.2–58.4V and must be charged to 58.4V; a lead-acid profile that floats lower will under-charge it, and a profile that pushes higher will over-charge the cells. Set the low disconnect at 43.2V. CAN or RS485 — which communications cable do I use? Use whichever port your hybrid inverter supports. CAN-BUS runs at 500 kbps and is common with 48V hybrid inverters; RS485 runs at 9600 baud and the pack provides dual RS485 ports so you can daisy-chain a parallel bank; RS232 is for monitoring or PC setup. Match the protocol and battery model in the inverter menu, otherwise the inverter cannot read the battery state of charge. How do I mount the 44 kg wall battery safely? Fix the supplied steel bracket to brick, concrete or studded timber with four expansion bolts and wall plugs — never to bare plasterboard. Lift the 44 kg unit with a second person, hang it on the bracket, and confirm it is seated before letting go. Re-check the fixings after the first week and keep the sides and top clear for ventilation. When I add a second wall pack, do I only connect the power cables, or does the dual RS485 communication link need to be daisy-chained too? Both. Wire the power bus positive-to-positive and negative-to-negative on the same 51.2V bus, using the identical GSK-51.2V-100AH model matched within about one month of production, at equal resting voltage, with each pack on its own breaker/fuse. Then daisy-chain the dual RS485 ports — RS485 runs at 9600 bps — so the packs share status and cell balance and the hybrid inverter and BMS manage them as one bank. CAN stays at 500 kbps for the inverter handshake. Up to sixteen packs reach 81.92kWh (51.2V × 1600Ah). Why can't I wire these batteries in series for a higher voltage? The pack is already a 48V-class (51.2V) unit designed for a 48V house bus. The supported expansion is parallel only — up to sixteen packs to 81.92kWh. There is no certified series tier to a higher voltage, and doing so would exceed the BMS and the inverter's rated voltage window. Do I need to ground the battery, and how? Yes. Connect the protective earth to the battery's grounding point and to the inverter earthing, and bond the wall-mounted metalwork as your local wiring code requires. Keep comms cables separate from the thick power cables to avoid interference, and always fit the DC fuse or breaker close to the positive terminal before energising the bank. What does the round LCD show during commissioning? The LCD displays state of charge, voltage and current. After switching the unit on with its power switch, confirm it reads around 51.2V at rest and that the inverter shows the battery state of charge over the comms link. Run a small charge and discharge test, then verify the 58.4V absorption and 43.2V cut-off are correctly applied. Can I install this battery outdoors? No. It is an IP54 indoor unit intended for a utility room, garage or boiler room — not for exposure to rain or standing water. It operates between −10°C and 50°C, but it must not be charged below 0°C because there is no self-heating element. In a freezing unheated space, bring the pack above freezing before charging. What current limit should I set on the inverter charge? Plan around the 50A rated charge/discharge figure; the 100A maximum is a short-time ceiling, not an all-day rate. Set the inverter's charge current to match the 50A rated limit so you do not push the pack beyond its continuous rating during daily cycling. How many packs can I wire in parallel, and what is the maximum bank? Up to sixteen identical packs in parallel, which reaches 51.2V × sixteen = 81.92kWh. The practical ladder is 1 = 5.12, 2 = 10.24, 4 = 20.48, 8 = 40.96 and 16 = 81.92 kWh. A two-pack install is the typical house; a sixteen-pack wall is a structural and comms project for a qualified installer. ## Sources and figures used in this guide The numbers below are the basis of the install guidance above.
