I have an off grid property with the Franklin Electric SubDrive SolarPAK solar well pump system. The controller/inverter/VFD appears to have died, and Franklin Electric wants about $6k for a replacement!
The motor is a three phase 1.5 hp model, and I have a 2kW array dedicated to the well. I have two extra panels (500W) that are connected to an Ecoflow Delta Pro for my modest power needs as I'm building a cabin. The well is about 400 ft deep I believe.
I'm not too keen on shelling out $6k for a part that may fail again. A friend is willing to give me a Growatt 5000ES, and I'm considering switching over to a single phase well pump powered by the Growatt. I'm not sure I even need a battery since the pump only needs to operate when there is sun. I gather the start-up surge current is an issue, but it seems the Grundfos SQ line with the soft start feature may be an option?
Interested to hear if this sounds like a good idea, or if some other setup would work better.
