Solar Power Solutions DC to AC Power inverters

A battery charger will normally draw power from a mains supply or generator, and charge a battery or bank of batteries, so too does Photovoltaic solar panels( Solar panels) convert energy from the sun into electricity, which needs to be stored in batteries.

Most electrical appliances and electronic equipment run on 230VAC power, which means in the case of a solar powered system, the power stored in the batteries needs to be converted from 12V/24V or 48V  DC to 230VAC.

There are DC AC power inverters which are large enough to accommodate this form of electrical supply.  DC to AC power Inverters probably originated because of Photovoltaic Solar power system-type applications, however it is not the case anymore. All DC AC power inverters  are not ideal or good for Photovoltaic solar power  system applications anymore.

Many of the available DC to AC power inverters are now used and designed for cost, mobility and various applications- From using a Laptop in your Car , to giving somebody time to watch TV at home, while Eskom is busy sorting its system out….

Why would DC AC power inverters for Photovoltaic Solar energy  systems be different then?Well to explain, let us first tell you some of the assumptions that might fit into your application:

All of these kind of systems, require quality products as well as system durability. System durability means, you want to look after your batteries as well as anything else. You might want a power inverter system that interfaces automatically with a generator and possibly other inputs such as Photovoltaic Solar Panels & Wind generator.

General experience shows that modified sine wave power inverters are not optimised for proper battery protection, although they do specify that they have a low battery cut out function , this tends to be at voltages 10.5V or in that vicinity, which is fine for occasional battery discharge, but for a permanent fixed installation, this is NOT acceptable. Batteries that reach that kind of discharge, will have their lifetime reduced from a possible 800 Cycles to only 50 to 100 cycles.


The higher – upper class true sine wave power inverters and inverter-charger units – do tend to have better battery discharge curves, some DC AC  power inverters even allow you to choose your disconnect battery voltages .

For system installations of this nature, you would like to have at least the following functions on your solar power inverters:


If your system , require inputs such as Solar Panels connections, Wind generator, Connection to a generator , then it is necessarily to ensure that these facilities are specified on the power inverter-charger.
