PVB residential energy storage systems are tailored to meet your home’s unique energy needs.
A residential energy storage system stores electricity generated by solar panels or the grid, allowing households to use clean energy anytime, improve self-consumption, and reduce electricity bills.
The system adopts lithium iron phosphate (LiFePO₄) batteries, offering high safety, long cycle life, and stable performance for residential use.
Yes. When paired with a compatible inverter, the system can provide backup power during grid outages, ensuring continuous electricity supply for essential household loads.
Yes. The wall-mounted design, compact size, and low noise operation make it suitable for indoor spaces such as garages, utility rooms, or basements.
The system integrates a smart BMS with protections against overcharge, over-discharge, short circuit, and over-temperature, ensuring safe and reliable operation.
By storing excess solar energy and supplying power during peak hours or outages, the system reduces reliance on the grid and increases household energy autonomy.
PVB offers a complete after-sale service includes installation, commissioning, maintenance, and battery replacements. Warranty covers repairs/replacements. Paid service available after.
