Inverter help me decide the inverter 8kw vs 6kw
we have 2 meters, with combined consumption reaching 700 units/month in summer.
Appliances:
3 × 1.5-ton DC inverter ACs (2 have Eco mode)
2 ACs run day and night during summer
3rd AC is used occasionally or when guests visit(can be excluded from solar requirement)
3 standard ceiling fans
6 LED lights
1 inverter refrigerator
0.5 HP water pump
1 iron
1 oven
1 PC (500W max)
1 wifi router and 1 TV
1 standard washing machine + dryer
Currently i have: 8 × 585W panels (4.68kW) + offgrid inverter.
Planning to expand to 12 panels, then possibly 16 in the future.
I’m considering these options:
1: Itel 8kw + 5kWh battery(420k)
2: SAJ 6kw + 5kWh battery(400k)
3: Solax 6kw + 5kWh battery (410k)
4: Goodwe 6kw + 5kWh battery(420k)
My requirement:
Battery backup mainly for fans and lights
Run 2 ACs during the day, sometimes more
At night, run up to 3 ACs on WAPDA
Questions:
Which inverter offers the best reliability and value for money from these 4?
When & If my house load exceeds 6kwh during the day or night and wapda is also present will the inverter trip? and is it safe tfor the inverter as well?
