Solar Power System
1. You can choose different photovoltaic modules from different suppliers
2. You can combine different energy sources such as PV, wind energy and hydropower to the current system.
3.You can expand or change the photovoltaic modules at any time
PWM solar charge controller:
The PWM charge controller is a good low-cost solution for small systems only, when solar cell temperature is moderate to high (between 45°C and 75°C).

How a solar system works?
1.Solar modules collect sunlight energy to generate DC electricity through the photovoltaic effect.
2.Solar charge controller, or charge regulator is basically a voltage /or current regulator to keep batteries from overcharging. It regulates the voltage current coming from the solar panels going to the battery.
MPPT: An MPPT, or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid. They can convert a higher voltage DC output from solar panels down to the lower voltage needed to charge batteries.
PWM: Pulse Width Modulation (PWM) is the most effective means to achieve constant voltage battery charging by switching the solar system controller's power devices. When in PWM regulation, the current from the solar array tapers according to the battery's condition and recharging needs.
3.Power inverter is an electronic device or circuitry that can convert direct current(DC) from DC source (Storage battery) to alternating current(AC). The input, output voltage and frequency, and overall power handing depends on the specific device or circuitry.
