Hi, I'm new here. I am planning my DIY solar system and seeking advice on which inverter to go with. I am undecided between the Growatt SPF 12000T DVM MPV & 2 of the EG4 6500EX-48.
The goal is to use the system as a UPS of sorts with solar/battery being the preferred input and only switching to utility when I drop below a minimum level of charge. Price between the 1 growatt and 2 EG4s is ~$300. There will be a large surge load (3 ton HVAC with soft-start kit [LRA can get as high as 60A @ 240V]). Today I am able to run the entire house with a 8KW genset and start the HVAC about half the time. Obviously there is some load management when on genset (we wont run the electric dryer, water heater, or oven at the same time) but otherwise it works.
Other things to consider:
Starting with 6KW of PV with later plans to scale up to 18KW (this will also require additional MPPT controllers).
I plan on starting with 3x EG4 5.12KW batteries with later plans to scale this up to 6.
Any and all input is appreciated!
Thanks,
