A very exciting project to power a beautiful charter yacht with a solar system of 1,5kW (12V). ExSolar’s team installed the complete system to power the boat for the Madagascar diving and fishing charter tours. The system consisted of: 6 x 250W solar panels 2 x MPPT solar chargers 60A 12-48V 8 x Solar Batteries Lead-Crystal 100Ah/12V 1 x Inverter/Charger MultiPlus 12/3000/120-50 230V Solar cable and connectors Battery cables Solar power board with mini breaker box Aluminium mounting frame for solar panels Accessories (screws, conduits, etc.)

An exciting project for the solar system in a residential property with a pre-paid meter. The challenge, as in many residential and commercial establishments, is to design a system that would be able to work with a prepaid meter. Pre-paid electricity meters do not see the direction of the current, so when the customer has a solar system that at any stage is overproducing the power and start to push back to the grid – the pre-paid meter sees that as a standard electricity usage and bills one for the energy the PV systems produces. To avoid this situation ExSolar connected the Fronius solar grid inverter to our very own Smart Energy Controller (Grid Tie Limiter), that has the ability to either re-direct the overproduced energy to specific appliance (like a geyser or a pool pump) or limit the production of the PV panels to meet the energy consumption needs of the client. The system consisted of the following: 12 x 300W solar panels and aluminium mounting structures 1 x Fronius 35V-1 Solar Grid Inverter (3.710kW) 1 x Smart Energy Controller (Energy Monitor for grid tie limiting) with an Energy Monitor WiFi Module Solar cable, connectors DC fuses, breakers Saddles, cable ties, insulating flashing, silicon sealant, raw bolts, mains isolator, bus bar cable Go to www.exsolar.co.za/blog/ to view other installations and references from happy clients. This 3kw solar panel system was installed by the proficient and friendly team at ExSolar for a family home in Durbanville. The system consisted of:
A 3.5KW project for the grid tie solar system in Durbanville, Cape Town The ExSolar team connected the Fronius 3.7KW solar grid inverter to an old energy meter system in order to push back excess power generated by the solar panels mounted on the roof to the grid. The system consisted of the following:
