LVTOPSUNLithium batteries for solar homes, shops and factories
Store solar power for the night and for power cuts, from 2.56 kWh up to a 261 kWh cabinet. Buy, design and install with TAMNIYOM, the official LVTOPSUN distributor.
Specs from the maker's website lvtopsun.com (checked 1 Nov 2026) and may change between batches. Ask TAMNIYOM about prices, stock and warranty terms in Thailand before you order.
Only models of the same voltage are compared, because the battery has to match the inverter. The 25.6V wall battery has nothing to compare with; see itsproduct card · “–” means the maker's page does not say.
Sizing
How many batteries do I need?
Slide to the energy (kWh) your home or shop uses after sunset. It uses the 90% usable capacity in the maker's specs and is only a first estimate. Send your electricity bill on LINE and the team will work out the real size and pick the inverter.
TAMNIYOM is the official distributor of both LVTOPSUN and Solis, pairs the two brands and teaches the installation every month. Low-voltage (L) inverters work with the 51.2V models and high-voltage (H) inverters with the HV models. The 261 kWh cabinet already has a 125 kW Solis inverter inside.
Other brands the maker's HV battery page says will work:
Deye
Megarevo
ATESS
Growatt
Before you buy, send your inverter model to the TAMNIYOM team so we can check that the battery's BMS talks to the inverter. LVTOPSUN also makes its own 15 kW hybrid inverter. See specs
