Solar panels produce a direct current which can be stored in solar batteries or used directly in a household or commercial building. For effective use the electricity has to be converted into usable alternating current with inverters.
Pure Sine Wave And Modified Sine Wave Solar Inverters
There are two forms of electric wave output generated by a solar inverter: pure or true sine wave and modified sine wave.
Solar inverters that produce pure sine waves are suited for homes that require an optimum performance for appliances such as TVs, computers and stereos.
Modified sine wave inverters are well suited to run greater appliances such as power tools and other motor driven loads, non-digital microwave ovens or lights.
Modified sine wave solar inverters are cheaper and can run most appliances. The disadvantage of using a modified sine wave solar inverter is that slight interferences can occur for televisions and computers. This however, will not damage the appliances.
Size of Solar Power Inverters
The size of solar inverters depends on what kind of appliances you want to run. Check first how many watts you need to produce, then buy the solar inverter with the capability to generate the right amount of power.
Combine Your Solar Inverters With A Solar Charge Controllers
Inverters draw solar energy from the solar panel or the solar battery, where surplus energy is stored. Usually the solar inverter does not run the battery dead, but will sound an alarm or turn itself off in time. If you want to have better control over your battery status, you should install a solar charge controller that is reliable such as an MPPT (Maximum Power Point Tracker) which optimizes the match between the solar array from the panels and the battery bank (ie. how much utility remains in the battery).
We recommend that you consider your various options to ensure you get the best quality saving you time and money later on.
