Off-grid Residential Energy Storage System -2kW/2.4kWh
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.
Features:
• All-in-one system integrated with MPPT, controller, inverter, battery;
• Multiple protections: like low/overvoltage; low/ over current; temperature; AC input; short-circuit...
• With DSP control chip, improving the system’s integrability, reliability, accuracy, and programmability;
• Automatic identification and selection mode for solar, mains and battery;
• Pure sine wave, high conversion efficiency, and reliability;
• With 4.3-inch touch LCD display board for easy checking parameters;
• Intelligent BMS system for management and protection;
• External optional communicate port like RS485;
• USB output (12VDC/5VDC);
• Easy wiring;
Applications:
It can be used for many different energy storage applications: Home appliances in remote areas where always power off; Villa appliances as bank-up power for the night. As emergency backup power with or without solar.
It is highly recommended for residential/home energy storage to maximize solar usage, lower electricity bills, and increase energy independence.
