It depends on the goal. 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.

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.

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.

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.

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.

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.

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.

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.

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.

The box contains the wall bracket, expansion bolts, a power cable, a communication cable and the manual. At €849.99 (struck from €1,250) this is cheaper than LiTime 48V 100Ah (€1,199.99) and ECO-WORTHY Cubix100 (€1,009.99) and near Redodo (€855), but it is modestly dearer than the established Pylontech US5000 4.8kWh (~€718) — GSIKE counters with a little more usable energy (5.12 vs 4.8kWh), a dedicated wall mount, the round LCD and 30-day returns, while Pylontech has the longer inverter-compatibility track record.
