Off-grid Series Energy Storage System for home

Range Summary:

FnS’ off-grid energy storage system has been specially developed for the production and storage energy for residential or microgrid applications. Which combined with PV modules, inverter, MPPT charger, CPU, and lithium battery, can store and provide power to home appliances.

These series have four options that can choose from 2KW to 6KW, the integrated MPPT search maximum power circuit by voltage and current of the PV module, to provide the maximizing energy delivered. And the independent modularization design improves the reliability and extendibility greatly. The pure since wave can provide stable powers for home electronics with low loss, high conversion efficiency.

The multiple functions like strong shockproof, solar/grid/ battery complementary, automatic battery charging & monitoring, auto-selection mode, AVR functions, etc., which can meet different customer’s demands on various applications.

In addition to providing economic incentives, residential energy storage users also realize that the battery energy storage system registered in the public utility company project still has the ability to provide them with electricity when the power grid is dispatched, so battery-related flexibility may add value to residential users.
