Good day all, I need help in laying out the best way for a solar system for my house.
I work as an expat and therefor I am for long periods not at home. My wife and 3 pre-teen sons is alone then as well. My security systems, cameras and all as well entertainment such as playstation and, televisions and internet must be on and running.
We have a solar/gas geysers and a gas stove. So usage from the grid is minimal. I installed an Efergy Power monitor and it register an average of 11kWh per day. Never over 12kWh per day and that is when it is a school holiday and the boys are 24/7 on the games and televisions. School days, monday to thursday, there is only a few hours of television after homework and sport. A maximum of 2.5kW per hour is used when my wife is in the kitchen using the microwave, the boys are on their televisions and house cleaning is being done using vacuum cleaners, etc.
I searched the internet and found a system that I think will help us cope, at SolarAdvice and it consists of the following;
1 x 4.6kW Goodwe ES Hybrid inverter – 2 x MPPT inputs with a Max of 6500Wp NRS approved (National regulation standards)
1 x Cable Pack
10 x 330W JA Solar PV modules
1 x Complete pitched roof Solar mounting kit (to be determined)
2 x BYD B-Plus 2.56kWh LV Battery 100% DOD – 5.12kwh
1 x BYD B-BOX Cabinet, (4 x 2.5) incl. BMU
1 x MC4 Connector Twin Pack ( Kit 1 )
1 x K&N Dual String DC Switch Disconnector 25A 220V
2 x K&N Single Phase AC Switch Disconnector 25A
1 x 4mm2 single-core 100m cable – Black
1 x KETO Battery Disconnector with 125A Fuses
I am also thinking of adding 2 x 1500W/48V wind turbines, after I've added the second string of 10 x 330W panels, to complete the system in the future. I've bought a stand which is high up a hill where there is wind in an abundance. I would like to utilize the wind turbines mainly for cloudy and windy times and especially through the nights instead of buying bigger battery bank.
Could you all please assist and advise me in how to go about the whole layout. I would also like to know if anybody knows about good electricians/installers that can do a certified grid tied installation.
Thank you all in advance. I LOVE THIS FORUM.
