Inverters

Sunray Solar have a comprehensive stable of versatile inverters to meet the wide variety of power requirements. We are proud to have The Schneider, Victron and Voltronics quality products in our range, as well as economy solutions for the simpler installations where complex features are not required.

Off Grid Inverters.

Off grid inverters are used where there is no incoming utility supply. The inverter will source its power from a battery providing DC and convert it to conventional 230v AC to power appliances or lighting. Solar panels can be used to charge the battery, and a solar charge controller or regulator will also be required to ensure the correct charging of the battery by the solar panels.

Off/On Grid Inverters.

Where customers have an incoming AC supply either from the supply authority (BPC or Eskom), or generator, we have inverters which can switch between each incoming power source and the battery supply without interrupting power or loss of data. The inverters can be set to use whichever power source as priority, and which of the power sources to switch to under various conditions. A useful feature on some of the higher end inverters is that the inverters can shed loads, and also share the loads between the available power sources.

Hybrid Off/On Grid Inverters.

These inverters have the added convenient facility that allows the Solar Panel output to be connected directly to the inverter making the use of an expensive charge controller not necessary. The inverter has both an AC charger to charge the battery from the incoming AC supply, and a DC charger which charges the battery from the solar panel input - one step closer to total automation.

Grid Tie Inverters.

These intelligent inverters connect directly to the Solar Panel input and supply AC directly to the load. They can be set up to export excess energy produced by the Solar Array back into the incoming AC supply, thus saving you on electricity bills. Unfortunately this function is not yet allowed by BPC or Eskom, but it will be legalised shortly. This will enable power users who have a incoming supply from Eskom or BPC to generate their own power, and if there is any excess, to sell it back to Eskom or BPC to reduce their electricity bills. Owners of this type of installation must be cautious to ensure that their Grid Tie inverters have the necessary protection functions to comply with local regulations.
