Model LV-AST-3H12K5.32Aa. A residential BESS with integrated inverter, high-voltage box and LFP battery modules in a single modular unit. Available in 1 layer (10.24 kWh) or 2 layers (15.36 or 20.48 kWh). 12 kVA grid output, 2 MPPT inputs, <20ms EPS switchover. IP65. 7-year warranty.
1 layer = 10.24 kWh. 2 layers = 15.36 or 20.48 kWh. Single module is 102.4V / 52Ah LFP.
Integrated 3-phase inverter. Grid voltage 400V / 360–440V. 50/60Hz. AC output topology 3W+N+PE.
Automatic switchover to backup in under 20ms. 12 kVA EPS rated output, 17.3A max, 400V rated.
7-year warranty handled directly by Charania Renewables.
Each layer holds 2 modules. The base unit ships as 1 layer. Adding a second layer increases capacity — choose either the 307.2V or 409.6V configuration depending on your site requirement.
