* 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.
Who a 16 kWh battery suits
16 kWh suits larger homes, heavier loads such as air conditioning or a water pump, and longer outages. With 314 Ah cells, one unit stores about 5% more than a 300 Ah battery at the same voltage: 16.08 kWh against 15.36 kWh.
For garages and covered outdoor spaces, choose an IP65 model: KNY 51314, ESS-D, ESS-E or ESS-H. ES-LV-16, ES-BOX-16 and the ESS models also have a built-in aerosol fire extinguisher.
How long does 16.08 kWh last?
| Average load | Example | About |
|---|---|---|
| 300 W | Fridge, lights, Wi-Fi and TV | 42.9 hours |
| 1,000 W | An example evening load at home | 12.9 hours |
| 2,000 W | With one air conditioner or a water pump | 6.4 hours |
A rough guide: 12.9 kWh used (80% of 16.08 kWh), before inverter losses. Real runtime depends on the inverter, the loads and the temperature.

View specifications →16 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 314 Ah battery?
51.2 V × 314 Ah = 16,077 Wh, or 16.08 kWh. At 80% depth of discharge, about 12.9 kWh is used in each cycle.
What is the difference between 300 Ah and 314 Ah?
The cell size. 314 Ah cells give 16.08 kWh at 51.2 V; 300 Ah cells give 15.36 kWh. The cabinet is often the same: KNY 51300 and KNY 51314 share an 800 × 580 × 255 mm body.
Which 16 kWh model lasts the most cycles?
ES-LV-16 and ES-BOX-16 are rated for 8,000 cycles at 25 °C and 80% depth of discharge. The other models are rated for 6,000.
Which models can go in a garage or covered outdoor space?
The IP65 models: KNY 51314, ESS-D-16, ESS-E-16 and ESS-H-16, and their 15 kWh versions.
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.
Which documents come with it?
CE, MSDS and UN38.3 are listed for every model on this page. IEC 62619 is also listed for ES-LV-16 PLUS, the ESS-D, ESS-E and ESS-H models and KNY 51300. 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.
