Product Description
Specifications & Configurations
Off-grid photovoltaic power generation system is applicable to areas without grid connection or power instability. Off-grid photovoltaic system is usually composed of solar module, controller, inverter, battery group and support system. They generate dc power directly through the day or stored in batteries and are used to provide power at night or on cloudy or rainy days.
Off-grid photovoltaic systems are independent solutions because they can be installed in most places and are easy to maintain locally. They are reliable, clean and cost-effective compare to diesel generators.

FAQ
Q1: What are differences among grid-tied, off grid and hybrid solar power system?
A1: Grid-tied system works based on the national grid. If there is without the national utility, the system can not word.
Off grid system can word without the national grid, but if there is national grid, which can be a back up power for the off grid system
Hybrid system, which combine the function of grid-tied and off grid. All in all, it's a grid-tied system, but can also store the power in the battery.
Q2: How about the leading time?
A2: After receiving deposit, 20-30 days.
Q3: How many years of warranty for the solar system?
A3: For the each of accessories, the warranties are different. Solar panel has 10- years linear output warranty and 25years life span. Contorller, inverter and battery has 5-10years warranty years warranty.bracket has 10 years warranty.
Q4: How to design a suitable solar power system?
A4: Just contact our sales engineer, who will design the full set of solution for you based on your really needs with the most competitive cost.
