LiFePO4 batteries: how much capacity for your inverter
We ship LiFePO4 (lithium iron phosphate) into 9 out of 10 new solar installs in 2024-2026. Lead-acid AGM is gone from our shop: 50% depth-of-discharge versus 90-95% on lithium, three times fewer cycles, 5-7 year service life versus 15-20. The one weak spot of LiFePO4 (poor charging below -10°C) we cover with a built-in heating board or by mounting the bank in a heated cabinet.
Our typical customer this year: a 100-150 m² house with a 5-8 kW hybrid inverter. We ship one 10 kWh module for overnight autonomy: fridge plus router plus a few lights. If they want to survive a full sunless day, we go to 15 or 25 kWh, or cascade two 10 kWh units. We ask up front: which inverter do you have. Because the battery BMS and the CAN/RS485 protocol must match the inverter firmware. Deye works with one list. Veichi with another. Felicity is more universal but still has its caveats.
What we ask before you order LiFePO4
First question: which inverter is installed or planned. Without that we will not size the capacity. Second: where it sits. If the bank lives in an unheated outdoor cabinet, the internal heater is mandatory. Otherwise winter charging stops below -5°C. Inside a warm utility room any model from our catalog will do. Third: planning horizon. One battery now or cascade expansion later. Felicity LPBA and LPBF allow parallel banks of up to 16 modules. Rosen in rack format scales by adding units. Veichi VCLB is easier for wall mount as a single block.
Manufacturer warranty on LiFePO4 in our shop runs 5 to 10 years. Felicity LPBA carries 10 years. We ship same-day from our Kyiv warehouse. Regional delivery via Nova Poshta or Delivery in 1-3 days. Before any order we double-check the battery-to-inverter protocol against the manufacturer datasheet. Compatibility mistakes are rare among our customers, but the cost of getting it wrong is high.
