KNY 51 series white 10 kWh floor-standing LiFePO4 battery
51.2 V · 200 Ah · 10.24 kWh

10 kWh home batteries, 51.2 V 200 Ah

Four ways to put 10.24 kWh in a home: an IP65 floor unit, two touch-screen cabinets and a stackable system with its own inverter. All are 51.2 V LiFePO4 and work with 48 V hybrid and off-grid inverters.

* Cycle life at 80% depth of discharge (25 °C where stated). All 51.2 V models use CAN and RS485 to talk to the inverter. Data from the 2026 product catalogue; we confirm the current datasheet with every quotation. “Ask us” means the catalogue does not state it.

Sizing

Who a 10 kWh battery suits

10 kWh is a common size for a family home with rooftop solar. It can store the afternoon's surplus and run the home through the evening, and keep essential circuits going through long outages.

Two 5 kWh units in parallel give the same capacity. One 10 kWh unit means fewer cables and a single BMS; two 5 kWh units are lighter to handle and can be bought one at a time.

How long does 10.24 kWh last?

Average loadExampleAbout
300 WFridge, lights, Wi-Fi and TV27.3 hours
1,000 WAn example evening load at home8.2 hours
2,000 WWith one air conditioner or a water pump4.1 hours

A rough guide: 8.2 kWh used (80% of 10.24 kWh), before inverter losses. Real runtime depends on the inverter, the loads and the temperature.

Questions

10 kWh batteries: common questions

48 V or 51.2 V? A LiFePO4 cell is 3.2 V. Sixteen in series make 51.2 V, which is what most “48 V” lithium batteries are. They charge to 58.4 V at most and cut off at 44 V, which suits 48 V hybrid and off-grid inverters that support lithium batteries.

How many kWh is a 51.2 V 200 Ah battery?

51.2 V × 200 Ah = 10,240 Wh, or 10.24 kWh. At 80% depth of discharge, about 8.2 kWh is used in each cycle.

Is "48 V 200 Ah" the same as 51.2 V 200 Ah?

Usually, but check the kWh figure. Many "48 V 200 Ah" listings are this same 16-cell, 51.2 V battery (10.24 kWh). Others are 15-cell packs at 48 V, which store 9.6 kWh.

Is a 51.2 V battery the same as a 48 V battery?

In practice, yes. A LiFePO4 cell is 3.2 V, so 16 cells in series give 51.2 V. That is what most batteries sold as "48 V lithium" are, and they work with 48 V hybrid and off-grid inverters that support lithium batteries.

Will it work with my inverter?

Our 51.2 V batteries talk to inverters over CAN and RS485, and most models also have RS232. Send us the inverter brand and model and we check the communication protocol before you order.

One 10 kWh battery or two 5 kWh?

One 10 kWh unit needs fewer cables and has one BMS. Two 5 kWh units weigh less each (KNY 51100 is 52.6 kg; KNY 51200 is 101 kg) and can be bought one at a time. Both set-ups run in parallel with more units later.

Which documents come with it?

The documents listed for each model are in the table above: CE, MSDS and UN38.3 on all four, and IEC 62619 on ES-LV-10 PLUS as well. We send the current datasheet and certificates with every quotation.

How are the batteries shipped?

LiFePO4 batteries travel as Class 9 dangerous goods, with the UN38.3 test summary and MSDS. We ship by sea from China to your port, from sample orders to full containers.
