Solar Power System and Its Different Usesby Jenny Zhai Sales Manager at Lorraine Trade Limited
Systems which allows you to store your solar power in batteries for use when the power grid goes down or if you are not on the grid. Hybrid systems provide power to offset the grid power whenever the sun is shining and will even send excess power to the grid for credit for later use. Provides power for your critical loads when the power grid is down is known as Off Grid Inverter.
Solar Power System is the use of the sun’s energy either directly as thermal energy (heat) or through the use of photovoltaic cells in solar panels and transparent photovoltaic glass to generate electricity .
Standard photovoltaic solar panels are the most efficient application of photovoltaic. However, photovoltaic glass allows generation from surfaces like building windows that were previously incapable of anything but passive solar energy and also enables other options, like color choices. Other technologies include low-tech solar heaters created from recycled cans that provide an inexpensive source of heat.
The power source is PV, wind, hydro, fuel, or utility grid. Its purpose is to keep your batteries properly fed and safe for the long term.
Charge Controller basic functions are quite simple. Charge controllers block reverse current and prevent battery overcharge. Some controllers also prevent battery over discharge, protect from electrical overload, and/or display battery status and the flow of power.
The control of battery charging is so important that most manufacturers of high quality batteries (with warranties of five years or longer) specify the requirements for voltage regulation, low voltage disconnect and temperature compensation. When these limits are not respected, it is common for batteries to fail after less than one quarter of their normal life expectancy, regardless of their quality or their cost. A good charge controller is not expensive in relation to the total cost of a power system. Nor is it very mysterious. I hope this article has given you the background that you need to make a good choice of controls for your power system.
These charge controllers give approx 30% more power than a PWM charger and you can connect high voltage panels to lower voltage battery banks.
In a normal charger the battery acts as a resistor reducing the amount of power you can get out of the panels, these chargers use Multi Power Point Tracking (MPPT) which keeps 2 separate circuits for the panels and batteries allowing upto 30% more power to be collected from the panels.
Using higher voltage on the panel side will also benifit by less volt drop and can use thinner cables. On large arrays we run everything at 100V - 150V that is MPPT Charge Controller.
“Cnbou” produces different solar power systems like Off Grid Inverter Charge Controller MPPT Charge Controller and lots more at an affordable price.
