hmmm in this situation solar panel +battery + 12v dc LED… will relieve inconvinient from the dark
200w solar panel + 200AH battery + battery charger ( charge battery bank from the grid when electricity is on ) + 1000 watt inverter… will save the day
we can turn on the light, barber shop tool, cahsier machine, laptop, 35-100 w cooling fan ( AC are not possible because it need more than 5 KWH of battery bank )
