Hi all -
First time stumbling upon this forum. I'm in the middle of the process, having just received permits and now awaiting installation timing. In the final design recommendation, I was surprised to see that the team recommended 2 SolarEdge7600 inverters for this install, for a total AC size of 15.2KW with estimated DC production at 16.12KWh. The 15.2KW output exceeds Massachusetts' net metering cap of 10KW, so I'll be taking a bit hit in the net metering benefit... which may be offset by the extra production, but more on that in a second.
Frist Question: When I asked why I can't use one SolarEdge10K, I was told that 1 inverter can't handle that size system? Is that true? I was told I'd have to drop down to the 12.2KW system size if I wanted to stay under the 10KW cap with one inverter, but I'd obviously lose a lot of production. Is there a happy medium to get me the maximum DC production without exceeding the 10KW AC net metering cap?
Second question: Is there a simple calculator out there that anyone can share, where I could more easily decide on the benefit of over-producing (and taking the "penalty" on the wholesale rate vs. retail rate for net metering in the month I over-produce) vs. staying under the cap and getting the maximum rate on the net metering? This is probably a Mass. specific question that also factors in the SMART program, but I'm hoping someone else was already in the same position I am.
Love the forum, thanks in advance for any responses!
