[RE-wrenches] Non-battery string inverter options?

[William Miller]

Friends:



Now that RSS is required on almost every installation, I am having trouble
finding a plain old, non-battery, non-MLPE string inverter.  This is for a
ground mount with the inverter mounted to the rack-- the only scenario I
can imagine that does not require RSS.  I don’t need or want battery
capability, now or in the future.  The project does not have shading issues
and the inverter will be mounted on the array, so no version of MLPE is
needed.



My usual go-to would be the legacy SMA Sunny Boy series.  I can’t dine one
for sale and I am getting the impression these are no longer available.



What might you recommend for this new installation?



This brings up the question:  Of all the Sunny Boy installations I  have
out there, the next time one fails, what am I going to replace it with?



The new Sunny Boy Smarty-Pants series is not yet shipping, it is very
expensive and to replace a grid-connected inverter I don’t need battery
capabilities.



I can’t use Solar Edge because I won’t want to unwire a complete array and
add optimizers.



I am not that taken with Sol-Ark, not only because it includes the word Arc
in its name.  I don’t need the battery capabilities, AC load center or any
of the other complexities.



Any advice is appreciated.
