How to Size a Solar Charge Controller?
A solar charge controller is used to manage the power from the solar cells to charge the batteries and supply the load in the solar power system. The charge controller protects the batteries from overcharging or deep discharging, so as to guarantee the safety of the batteries, increase the service life of batteries and then improve the solar system performance. So, really it's worth doing more investigation in your solar system for best sizing a proper solar charge controller. It is the key for longer life and higher efficiency for your battery bank as the charge controller optimizes the power and voltage coming from your solar panels to provide best charging voltage and current to the batteries.
How to Read Solar On Grid Inverter Data Sheet?
What is the on-grid inverter data sheet? It's a sheet shows the on-grid inverter specs, so can judge if the inverter can be used in our system or not. It's an important matter to be able to read the sheet and understand it before buying the on grid inverter.
What are the Advantages of Inverter Generators?
What are the advantages of Inverter Generator? Inverter Generator provides more electrical power for the same amount of the fossil fuel compared to traditional generator, in other word, it achieves higher efficiency (approx. 30% higher). Inverter Generator is quiet with smaller size and weight. It doesn’t pollute the environment because it consumes less fuel. It can handle motor inrush/surge current at starting period efficiently without oversizing, so lesser Inverter Generator power capacity will perform better than larger traditional generator capacity in cases of using the generator to feed motor-based load.
On Grid Solar System and Win-Win Relationship
It's a solar system that is connected and synchronized with the power grid. So, the electrical load will be fed from both sources which share to each other in feeding it. In cloudy days or at night where the solar system generation is low or even is not exist, the electrical load takes its power requirements from the power grid. And in sunny days where solar generation exceeds load power requirement, the load take all its power requirement form the solar system and surplus solar generated electricity will go to the power grid to be used elsewhere.
Brief Introduction to On-Grid Inverter
The on-grid inverter must match grid sine wave phase and voltage, so can inject the AC current into it. The most important feature of such inverter is its ability to work without batteries, it based on solar panels or wind turbine and power grid presence only, so if the solar energy or wind energy are not sufficient to feed the load, it consumes his power requirements from the power grid.
