Hoymiles announced the launch of the LB-(5-12)S-G2 series of low-voltage stackable batteries for residential and small commercial energy storage. The company describes the range as deep cycle, high-capacity LFP (lithium iron phosphate) stackable batteries1.
Each LB-G2 module has a capacity of 5.12 kWh, and up to four modules can be stacked in a single battery rack, giving 20.48 kWh per rack. The series supports five racks in parallel, which the company says allows capacity to reach up to 102.4 kWh1.
| Model | Rated capacity (Ah) | Total energy (kWh) | Number of modules |
|---|---|---|---|
| LB-5S-G2 | 100 | 5.12 | 1 |
| LB-10S-G2 | 200 | 10.24 | 2 |
| LB-15S-G2 | 300 | 15.36 | 3 |
| LB-20S-G2 | 400 | 20.48 | 4 |
Hoymiles states that no external wiring is needed, that the battery is placed on the ground and additional modules stacked as required, and that the monitoring app automatically detects Hoymiles inverters and batteries without additional configuration1. On safety, the company says the battery stops charging when it reaches 50°C and stops discharging at 55°C, that an aerosol fire protection mechanism activates automatically if a module reaches 170°C, and that the IP66 enclosure rating allows indoor and outdoor use1. A self-heating module activates at 0°C and can heat the battery to 10°C within half an hour1.
The batteries are designed to work with Hoymiles microinverters and energy storage inverters. The company also lists a high-voltage HB-G2 battery range, starting at 11.52 kWh with three modules and expanding to 23.04 kWh with six modules in a single rack1.

Why it matters for households
For a household, the practical question with any modular and stackable battery system is how much storage can be added later without replacing what is already installed. Hoymiles gives a per-rack figure of 20.48 kWh and a five-rack ceiling of 102.4 kWh, so the range spans a single-module installation up to a size well beyond typical domestic demand1. The company positions the LB range for residential use and for small commercial projects such as hotels and restaurants1.
The stated operating limits and enclosure rating bear on where a battery can be sited and how it behaves in a cold or exposed position, which affects how much of a home's demand can be met from stored solar rather than imported power. The company says the batteries work with its microinverters and energy storage inverters to boost self-consumption and reduce energy costs1. Hoymiles is listed among home battery storage manufacturers, and its storage products are covered in the site's guide to Hoymiles storage systems for the home.
