Newly installed solar. The CES came back yesterday. Noticed the CES says 2 strings but the install is only 12 panels on one string.
So I went down the rabbit hole of checking whether I’m losing out on production (I definitely am) then whether it’s a dangerous install.
Turns out, the installer used a different panel than quoted, which in theory is beneficial to me. But the maximum current on those panels is 15.46A (16.52A short circuit) vs 13.18A (14.06A short circuit) quoted. The inverter only support 15A maximum and has a 18A short circuit. In short, moving to 2 strings would not solve my issue (because it’s over ampage not voltage)
At first glance this seems non-compliant?
Called ESV, they said the inspector who fucked up the CES is definitely worth a complain, but not sure if install is compliant without a site inspection.
Looking for advice on what to do next, do I get the installer to come back and fix it, if so, how? Do I leave it as is? Thanks
