The battery is the main component of your power station. Monitoring means knowing the state of charge in your battery. You can choose a voltmeter or use a purpose built monitoring system.
Using a 12 volt battery full of charge let’s say … 120 amp/hours.
If we measure the voltage of fully charged 12 volt battery with nothing connected it should be around 12.6 volts.
If we connect a reasonable load to the battery the voltage will drop to around 12.1 but the battery is still full of charge at this point.
If we connect a charging source to the battery, for example an 80 watt solar panel, the voltage will rise to about 15 – 16 volts.
If the battery was flat we might see the following:
- No load: 12 volts
- With load: 11.0 volts
- Charge connected: 13 volts
Solar Power can work well for most items except large electric appliances (water heater, clothes dryer and electric stove).
The basics of solar power:
Using solar power to produce electricity is not the same as using solar to produce heat.
- Solar thermal power is applied to produce hot fluids or air.
- Photovoltaic power is used to produce electricity.

The inverter 12 to 220Volt transforms the battery current to 220V to use in equipment operating at 220 volts. Ideal for television, computer, mobile phones, etc… , compressors, refrigerators etc. …
Most solar energy systems generate DC current which is stored in batteries. Nearly all lighting products, appliances, motors, etc, are designed to use alternating current, it takes an inverter to change the battery-DC stored at the standard power (120 V AC, 60 Hz).
In an inverter, a direct current (DC) is moving back and forth to produce an alternating current (AC).
