About modual
modual AG develops and manufactures modular battery storage systems in Switzerland for private households, agriculture, commercial and industrial applications. At its core is the second-life strategy: high-quality batteries from electric vehicles get a second life as stationary storage. Every battery cell undergoes rigorous testing before being installed in a storage unit. The company develops hardware and software entirely in-house – from circuit boards to cloud AI – including its own battery management system (BMS) that monitors every cell. The product range includes AC and DC storage systems (Series Basic, 11.5–46 kWh), AC sets with Solis hybrid inverter, and the Series Pro AC all-in-one wall-mounted storage unit (35–210 kWh usable) based on complete EV high-voltage battery packs. Applications include self-consumption optimization, peak shaving, grid services, ZEV/vZEV billing, off-grid island networks, e-mobility and backup power. Distribution in Switzerland is handled by the distributors Krannich Solar and Otto Fischer.
