Specifications

The functions of  components in the Solar off-grid PV system:
1. Solar panel (solar module): it is the most indispensable and valuable part of the solar power system, plays a role to convert the  solar radiation to electricity energy for storing in storage battery, or  driving the loads directly.
2. Solar controller: control the charging and discharging of battery, and provide over-charging and over-discharging protection for the storage battery.
3. Battery group: adopt popular maintenance free gel batteries or lead-acid batteries for storing electrical energy, and discharge electricity for loads
4. Inverter: It is used to convert DC to AC for AC loads, such as, invert DC12V/24V/ 48V to AC110V/220V/230V.
 
The information below will be required for the design of Solar Power System:
1. Where will the solar power system be installed? The solar radiation in this area.
2. How many KWH need the system to provide per day?
3. What about the Max load of the solar power system?
4. What is the output voltage, DC or AC?
5. What about the backup rainy days for the solar power system?
