Household Inverter丨Off-Grid Inverter丨BK-SCMAX-11KVA

Product Overview

The BK-SCMAX-11KVA is a next-generation wall-mounted off-grid all-in-one inverter. It integrates dual-MPPT solar controllers, a pure-sine-wave inverter, an intelligent battery management system and UPS-grade switching into a single unit. Up to six devices can be paralleled to reach 66 KW. Measuring only 600×425×150 mm and weighing just 21 KG, it can be wall-mounted and commissioned in 30 minutes, delivering 24-hour stable green power for homes, small commercial sites and off-grid micro-stations.

Application

• Premium villas & estates

20 KWh battery bank + 11KW inverter to achieve 70–90 % self-consumption.

• Off-grid or weak-grid areas

Micro-grids for villages, ranches and islands, powering water pumps, air conditioners and processing equipment.

• Small commercial premises

Convenience stores, clinics, EV charging stations with automatic backup, reducing diesel dependence.

• RV & mobile storage

2–3 units paralleled for a 15 KW-class mobile power supply for large motorhomes and campsites.

• Emergency backup

Paralleled with diesel generators for peak-shaving, cutting fuel consumption by 30–50 % and reducing noise and emissions.
