I am constructing my second powerwall 100p14s, initial one up and running for 2 years without much issues. Using nine 280W rooftop solar panels and a PCM 60X charger, and inexpensive night grid power ($0.15 per KWhr) to charge up, and using a Schneider Conext 4048SW inverter. Electrician has helped me create a separate panel to power household lights, a MW oven, a computer, and a refrigerator, and it seems to power all day without issues. I use grid power between 11 pm and 7 am as it is so inexpensive.
With my second powerwall, it will also be 100p14s, so will be doubling my storage space, and will be able to add a lot more loads to the system. Am not going to try to power any 220volt appliances or air conditioners. Just the rest of the home's lights and more refrigerators and another MW oven.
My question is how to connect up and use this second wall, ie do I need another Schneider Conext 4048SW inverter and PCM 60X charger, or can I connect both powerwalls in parallel and use my current nine rooftop (maxed out) 280 watt solar panels and inexpensive nighttime grid power to charge both packs as a single 48v battery, now just with double the amperage? Would much prefer not purchasing additional inverter and charger...
Another question regards my other 45 rooftop 280W panels connected to SolarEdge Inverters, producing excess energy at times, fed back to the local power company and not reimbused. SolarEdge does allow for the use of a couple of commercially available powerwalls (Tesla and one other). Has anyone successfully connected a DIY Powerwall to one of these inverters? Asked this same question 2 years ago, and answer was no.
Appreciate any positive feedback.
