not).\u003c\/strong\u003e A \u003cstrong\u003e48V-class DC battery\u003c\/strong\u003e — nominal \u003cstrong\u003e51.2V\u003c\/strong\u003e from a \u003cstrong\u003e16S1P\u003c\/strong\u003e string — not a charger, not a solar charge controller and \u003cstrong\u003enot an inverter\u003c\/strong\u003e (no built-in mains outlet, no AC output, no MPPT). It holds \u003cstrong\u003e5120Wh (5.12kWh)\u003c\/strong\u003e; its \u003cstrong\u003e2560W rated\u003c\/strong\u003e continuous ceiling (50A) is where you plan ordinary loads, while \u003cstrong\u003e5120W\u003c\/strong\u003e (100A) is a short-time maximum, not a sustained rating. To run household AC you \u003cstrong\u003epair it with a separate 48V hybrid inverter\u003c\/strong\u003e over RS232 \/ RS485 \/ CAN and set that inverter's battery profile to 51.2V LFP with a 58.4V charge. It expands in \u003cstrong\u003eparallel only\u003c\/strong\u003e (already 48V) — never in series.\n\u003c\/div\u003e\n\u003cdiv class=\"specnote\"\u003e\n\u003cstrong\u003eSpecification note — read before you order, mount or commission.\u003c\/strong\u003e\n(a) \u003cstrong\u003eDimensions and weight:\u003c\/strong\u003e the manual dimensioned drawing is the headline: \u003cstrong\u003e640 H × 428 W × 160 D mm\u003c\/strong\u003e wall-mount (wall bracket ~409.5 × 322 mm) and \u003cstrong\u003e44 kg net (44 ±2 kg)\u003c\/strong\u003e. However, the product web table lists \u003cstrong\u003e740 × 515 × 385 mm\u003c\/strong\u003e and net \u003cstrong\u003e45.1 kg \/ gross 58.6 kg\u003c\/strong\u003e; the weight is within the ±2 kg band but the dimensions are materially different, so please confirm the true case and bracket cut-outs with the merchant before drilling.\n(b) \u003cstrong\u003eWorking voltage and parallel count:\u003c\/strong\u003e the manual working window is \u003cstrong\u003e43.2–58.4V\u003c\/strong\u003e (the web table prints a lower bound of 40V; 58.4V is the bulk\/absorption charge voltage).

For overnight essentials (fridge, LED lighting, router, boiler controls running roughly 0.5–1.5kW), one 5.12kWh pack gives about an evening of backup. If you want to run higher average loads, cover cloudy days, or back a whole house including cooking, add more packs in parallel: two units make 10.24kWh, four make 20.48kWh, and the ladder scales to 81.92kWh across sixteen units.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan this one wall battery run my whole house or a 5kW inverter?\u003c\/summary\u003e\n\u003cp\u003eNot continuously on its own. This pack is rated for 2560W continuous (50A); the 5120W figure (100A) is a short-time ceiling, not a sustained rating. A single 5.12kWh unit will under-feed a 5kW inverter for steady draws, though it can handle short surges. Plan ordinary household loads to about 2.56kW per pack and parallel more units if your inverter runs higher for long periods.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I connect it to my hybrid inverter — which cable and protocol?\u003c\/summary\u003e\n\u003cp\u003eUse the built-in RS232 \/ RS485 \/ CAN links (RS485 9600 bps with a dual port, CAN at 500 kbps) to a mainstream 48V hybrid inverter. Before commissioning, set the inverter battery profile to 51.2V LiFePO4 with a 58.4V charge voltage and a 43.2V cut-off.

For overnight essentials (fridge, LED lighting, router, boiler controls running roughly 0.5–1.5kW), one 5.12kWh pack gives about an evening of backup. If you want to run higher average loads, cover cloudy days, or back a whole house including cooking, add more packs in parallel: two units make 10.24kWh, four make 20.48kWh, and the ladder scales to 81.92kWh across sixteen units.\"}}, {\"@type\": \"Question\", \"name\": \"Can this one wall battery run my whole house or a 5kW inverter?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Not continuously on its own. This pack is rated for 2560W continuous (50A); the 5120W figure (100A) is a short-time ceiling, not a sustained rating. A single 5.12kWh unit will under-feed a 5kW inverter for steady draws, though it can handle short surges. Plan ordinary household loads to about 2.56kW per pack and parallel more units if your inverter runs higher for long periods.\"}}, {\"@type\": \"Question\", \"name\": \"How do I connect it to my hybrid inverter — which cable and protocol?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Use the built-in RS232 \/ RS485 \/ CAN links (RS485 9600 bps with a dual port, CAN at 500 kbps) to a mainstream 48V hybrid inverter. Before commissioning, set the inverter battery profile to 51.2V LiFePO4 with a 58.4V charge voltage and a 43.2V cut-off. This is a battery, not an inverter — it has no AC output of its own — and it does not include WiFi app monitoring, only a round LCD.\"}}, {\"@type\": \"Question\", \"name\": \"What charger voltage does it need — will my current charger work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It needs a 16S LiFePO4 charge profile with a 58.4V bulk\/absorption stage and a 43.2V lower cut-off. A generic 48V charger without that exact absorption setting will not fully charge the pack, and a 12V or 24V charger is completely unsuitable. Confirm the charger or hybrid inverter can deliver 58.4V before you buy.\"}}, {\"@type\": \"Question\", \"name\": \"Can I stack several of these in series to get a higher voltage?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No. This is already a 48V-class (51.2V) pack, so you expand in parallel only — never in series. Parallel stacking keeps the bus at 51.2V and adds capacity: one unit is 5.12kWh, two is 10.24kWh, four is 20.48kWh, eight is 40.96kWh and sixteen reaches 81.92kWh. You cannot series-stack it toward a 102V-class system.\"}}, {\"@type\": \"Question\", \"name\": \"How many units can I parallel before I hit the limit?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The on-page table and pack images support up to 16 units in parallel, giving 51.2V × 1600Ah = 81.92kWh. (A line in the body copy mentions a lower figure; we follow the table\/images and recommend you confirm the exact parallel limit with the merchant.) Use identical units and matched state of charge, and use the dual RS485 port to daisy-chain packs.\"}}, {\"@type\": \"Question\", \"name\": \"Is it safe to wall-mount a 44kg battery myself?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"We recommend a strong wall, the included steel bracket (~409.5×322mm) and expansion bolts into a solid substrate, plus a two-person lift given the 44kg weight. Plan clearances around the unit and the terminal cover, and follow the install guide for anchoring, grounding and cabling rather than hanging it on plasterboard alone.\"}}, {\"@type\": \"Question\", \"name\": \"Can I leave it in an unheated garage through winter?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"It operates down to −10°C and stores best between 0°C and 35°C, with an IP54 indoor\/sheltered rating. It has no self-heating element, so do not charge it below 0°C — if your winter room can drop that low, add heating or choose a self-heating rival. The manual's printed temperature labels vary; follow standard LiFePO4 practice and confirm derating with the merchant.\"}}, {\"@type\": \"Question\", \"name\": \"How long will 5.12kWh actually last on essential loads?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"At the nameplate: 300W lasts about 17 hours, 500W about 10 hours, 1000W about 5 hours, and the 2560W rated line lasts 2 hours. In practice a typical essential load of fridge, lighting, router and boiler controls sits around 0.5–1.5kW, so one pack comfortably covers an overnight outage; derate about 10% for the inverter, and parallel more packs for longer autonomy.\"}}, {\"@type\": \"Question\", \"name\": \"What is in the box, and how does the price compare to Pylontech or LiTime?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The box contains the wall bracket, expansion bolts, a power cable, a communication cable and the manual.
