Green energy system  2KW 3KW 5KW off grid pv array system with LifePO4 battery bank backup 

Solar System Components Function :

Solar Panel
Solar Panel is not only the major part, but also the most valuable component among the solar power system . its function is to convert the sun's radiant energy to DC power.

Solar Charge Controller
Solar Charge Controller, also known as "PV Controller", whose function is to adjust and control power and maximize battery charging power.Meanwhile it supply overall protection like short circuit,overload,reserve connection prevention, overcharge ,over discharge,etc. solar controller should also have temperature compensation function.

St ora ge Battery
Battery bank's main task is to stock unstable DC power from solar panels and provide stable DC power to inverter and ensure stable running of the loads at night and rainy days.

Cables and MC4 connectors
We choose special 4mm2 PV wires,battery cables and MC4 connectors for the connection of solar power system components.

Off-Grid Pure Sine Wave inverter
Off-grid inverter is the core component of off -grid solar power system,  its function is to convert direct current from battery bank into alternating current for loads to use. In order to improve the overall performance of photovoltaic power generation system to ensure long-term stable operation of the power station, the inverter performance is very important.

How does the solar system work?
This system not only has solar power system function, but also has city electricity complement function and UPS function:            
When there is sunshine, it will use sun power first;
When there is no sunshine, it will use battery power;
When there is no sunshine and battery power is used out, it will automatically use city electricity ( or diesel generator ) to charge battery and take the loads at the same time;
When the sunshine is coming, it will automatically take use of sun power again.

Q: What can be included for this system from Sunchees?
A: This system includes: solar panel, PV array combiner, Hybrid solar inverter with built-in MPPT controller, Maintenance-free Gel battery, Mounting structure, cables etc.

Q: Is the solution for complete set? If not, what else are needed?
A: Yes, we can provide complete set solution. If you don't need complete set, basic parts are available too.

Q: Is the system solution always the same? Can I customize one?
A: No. We have professional teams make solutions for our clients. Solutions are mainly customized based on different sunshine time and power consumption. Same power system may be with different configuration.

Q: Who will arrange the shipment?
A: We are doing FOB trade term. If you need, we could help you to arrange the shipment, we have  long-term cooperation with  good service forwarders.

Q: What's the difference between off grid and on grid solar power system?
A: Off grid solar power system doesn't connect to the power grid. In general, the system includes solar panels, charge controller, batteries and off-grid inverter. This system will convert the solar power into electricity and store in the batteries, and the batteries will supply appliances the electricity to work through the inverter.
On grid solar power system connects to the power grid. In general, it includes solar panels, grid-connected inverter, the solar power will be converted into electricity and the electricity will be supplied to appliances directly. When there is no sunshine, the power grid will take place of the system and supply appliances the electricity to work.

Q: Can the inverter switch automatically to national grid to protect batteries.
A: Yes. The inverter not only can connect to national grid but also can connect to third generator, as like diesel generator. When there is no sunshine and battery power is used out, the inverter will automatically switch to use national grid power and take the load and charge the battery at the same time. Please tell our sales before production.

Q: What is the lifetime of the solar power system?
A: Solar panel lifetime are 25 years, battery lifetime is 6~8 years. The whole set system can supply free power at least 6 years. When battery reaches its life expectancy, just change new one then the system will continue working. Sunchees always insists on high quality goods, we never sell cheap quality products that can only use few months. We are not doing one-time business!
