Residential Inverter丨Off-Grid And On-Grid丨BK-VII-10.5KVA

Product Overview

BK-VII-10.5KVA is a wall-mounted, three-phase-ready hybrid inverter-charger that unites dual MPPT solar controllers, a 10.5 KVA/10.5 KW pure-sine inverter, and a 48 V smart battery manager in a 14.5 kg, 130 × 390 × 537 mm chassis. It seamlessly toggles between on-grid feed-in (up to 10.5 kW) and off-grid backup (dual outputs: 10.5 KW + 3.5 KW), supports parallel expansion, and can be commissioned on a wall in 30 minutes—turning any home, workshop or micro-grid into a resilient, revenue-generating energy hub.

Application

• Luxury Villas / Large Homes

20–40 KWh battery + 10.5 KW hybrid inverter for 80–100 % self-consumption and net-metering revenue.

• • Small-to-Medium Businesses

Workshops, EV charging stations—sell surplus power while securing critical loads during outages.

• Off-Grid Micro-Grids

Rural villages, islands, telecom shelters—run entirely on solar + battery or blend with gensets for fuel savings.

• Construction & Emergency Sites

Hybrid mode with generator peak-shaving, cutting diesel use by 30 % and reducing noise and emissions.

• Retrofit & Upgrade

Drop-in replacement for existing grid-tie systems to add battery storage, backup power and load management without rewiring.
