Sungrow 10Kw Inverter: The Most Reliable Unit We've Installed (Honest Review by Solar Installer) 

Depends on the system size and bills

If your paying 60 a month for electricity the. Solar would be a waste of money. You never going to get that money back.

@@erwin734 Mine was 800 for 3 months. Just installed a 10kw system with a 10 kw inverter. Sungrow. Perfect so far

@@erwin734 If you genuinely have low power usage then you will never realise all the benefits of solar. However, how much of that frugal use includes rugging up on cold days and avoiding the air conditioner on hot days, or other compromises that you have learnt to keep your power bill under control? I have been there. My home is all electric (no gas) and recently has been upgraded to this 10kw Sungrow inverter, 25.6kw of Sungrow batteries and 18kws of panels. Wow! I can now heat and cool the whole home day and night, heat the hot water, all cooking etc without even thinking about running out or overloading the system, even in winter. I still find myself turning off lights out of habit, but I don't have to. I can also take long showers with plenty of hot water and never have to think about it. It is pushing about 30kwhs to the grid every day (in winter), so it will also pay some money back each year. And there is the peace of mind of having all that power even if the grid goes down in a storm. It is true I wont get all the system cost back, but the luxury of using whatever I want whenever I want is pure joy.
