What a swap over...we have a muni project where the higher voltage optimizers on the 480v inverter allowed us to minimize conductor sizing. New central inverter would need to support strings that use that size. And then the labor to remove all those optimizers! But we're replacing one of those inverters so I hear your argument.  Look forward to hearing your decision.

Around that time there were some issues with solaredge equipment..specifically bad optimizers the SE tech support affectionately dubbed "sleepy optimizers". We had one job from that production run that we replaced several of the optimizers on.. in general though we've had great luck with solaredge otherwise with very few optimizer failures and the occasional inverter replacement(always straightforward and timely processing of the RMA). Just my experience but this seemed like an appropriate time to chime in.

Wrenches,

We maintain a SolarEdge 119kW (564 panels) small commercial grid tied system without ESS that we did not install. We were brought in at the bitter end to commission and get the interconnection agreement with the power company all set up. It has been about 4 years and we have replaced 5 of the 7 inverters and what seems like an endless amount of optimizers. 

I am toying with the idea of proposing that we move away from SolarEdge. It seems ridiculous on the surface but so is the money spent by the client fixing this system 2 to 3 times a year. Regardless, financially it does not make sense but functionally it is incredibly frustrating for everyone involved to keep fixing this system.

What would you do?

Aloha,
