This is the simple dark detection switch using two non transistor,photo resistor,photo diode,12V relay and few resistors.With bread board and jumper wires all thanks to Senior Sales for supplies Lae based.

Try to explain solar charge controller,BMS,Bq Ic and more but🤣out of words.But take note it has settings for B1 or lead acid battery,B2 for Li-on and B3 for Lif4for.More typing errors ☺️

This simple set up cost you K170 if you are in Lae city.3x12V9Ah is K90,PmW charger 10A is K30 and solar panel 10W is K50.Untidy but yet to complete my house.

Eye blo tewel or man 😂😊🙏.Was able to get alone with friend of mine Kakas Irape to a local church to trouble shoot a audio amplier and a sound mixer.The bridge rectifier was at fault with no dc output and the amplier had over load at times and trip off the varector and when cool it came back on.I was suspecting the sound vacume tube (UK branded) must be at fault so later Ill do some research and see.Peace.

When to a family resident today and checked their freezer that stops working.The problem was the temperature control k**b was set at 5 or max beacuse others are not working (bimetal).So the compressor heat has transfer to the close cable and it got burn.After resolving I told to run it for some time if needed only.It has no over heat protection so caution must be taken.
