I have 21 10 year old 210 solar panels on a 4000w inverter and I added 6 more 327 panels in 2016 on a 3000w inverter. I want to add another 6 panels and wonder if I can use micro inverters for the 6 new panels instead of buying and replacing one of the existing inverters.
I would think replacing the 210W panels with 300+W panels and a new inverter would be easy if you could re-use the same racking.
I am seriously considering replacing my 9 year old and degraded 240W polysilicon panels with new ones, re-using the old Enphase Micro-inverters. The primary consideration is keeping the same panel frame size and 60 cell panel type so they drop in with no other changes.
Good chance. For the cost of 6 micro inverters and the trunk cable and all the other ancillary stuff you'd need you're almost at the cost of a 7.6kW SMA inverter that can handle ~11kW of solar. How does your solar play with your Powerwalls off-grid? New Rule 21 inverters are able to adjust their output so they're not just on or off.
