Two things decide which battery fits your inverter
A 48 V hybrid inverter takes a 51.2 V LiFePO4 module. From there, two questions: how much capacity your load needs, and whether pack and inverter will talk over the data bus. Capacity is arithmetic. Compatibility is not: the inverter has to recognise your pack in firmware and speak to its BMS over CAN or RS485. That second point is where installations go wrong most often, which is why we ask for the inverter model before you pay.
How many kWh to buy
Multiply the hours of backup you want by your average draw, then divide by 0.9. That 0.9 is the depth of discharge LiFePO4 makers build into their rated cycle life. Catalogue capacities run from 4.1 to 25 kWh, and the common step is the 5.12 kWh module, which you then parallel. We wrote up the calculation against a specific appliance list in home battery capacity calculation. The full selection walkthrough is in how to choose a battery for a hybrid inverter.
CAN, RS485 and when an external BMS is needed
On most modules here the BMS sits inside and brings out CAN and RS485. The inverter reads pack voltage, current and temperature, and holds the limits itself. There are exceptions worth knowing before you order. Deye BOS-G, BOS-G-PRO, BOS-B-PACK14.3 and BOS-A are listed in the manufacturer datasheet as modules without a BMS of their own. The BIOM HV modules (BAHV-100512-LFP, BAHV-300512-LFP, BAHV-314512-LFP) are run by a separate Biom Professional CB-HV-100 or CB-HV-160 over CAN 2.0. What a BMS does, and why a pack is not operated without one, we covered in BMS for LiFePO4.
Charge current: 20 A to 230 A
Charge current sets how fast the pack refills during the window when the sun is up or the grid is back. The lowest in this catalogue is Deye GB-LM4.0 at 20 A. The highest is Deye SE-F12 and SE-F12-L at 230 A. Within the 5.12 kWh class the figure is more modest, 25 to 100 A depending on model.

Dashes in the Felicity row mean the figure is absent from the manufacturer datasheet, not missing from our table.
What is in this category
36 models from five brands:
- Deye, the widest capacity range
- BIOM, including HV modules with an external controller
- Felicity, home to the largest single pack at 25 kWh
- Veichi, wall-mount modules at 5 and 10 kWh
- Rosen, rack and wall units at 100 and 200 Ah
Capacities: 5.12, 5.32, 6.14, 7.68, 8.7, 10, 10.24, 11.8, 12.5, 14.3, 15, 15.36, 16, 16.08, 17.5 and 25 kWh.
Two models run a different voltage. Most of the catalogue is 51.2 V for a standard 48 V inverter. But Deye BOS-A is 38.4 V, and Deye GB-LM4.0 runs 102.4 V. Neither fits an ordinary 48 V unit: they are bought for specific inverter series. Not sure? Ask us and we will check against your model.
We do not supply 12 V or 24 V. Need a 12 V or 24 V module for a camper, a boat or a router? That is outside what we stock. We carry 48/51.2 V ESS packs plus the two exceptions above.

For a solar array there are batteries for solar panels. All lithium by chemistry sits under LiFePO4, and the full catalogue under batteries. The inverters these packs work with are hybrid inverters, including 5 kW models. Panels sit under solar panels.
Useful reading: connecting several batteries, why 48 V and 51.2 V are the same thing, inverter plus LiFePO4 as a system, what drives service life.
Warranty and support
24-month warranty, delivery across Ukraine. Before you pay we check two things: whether your inverter works with the chosen module over CAN or RS485, and whether a separate BMS unit is needed. The inverter model is all we need for that. If the module is not on the compatible list in your inverter firmware, we say so before the order rather than after the install. Also in the range: Felicity LPBA48170, Veichi VCLB-10K-W01, the rack-mount Rosen BAT-51.2V-200AH-RACK and the wall-mount BAT-51.2V-200AH-WALL. Ask us about availability.
