[RE-wrenches] EG4 Praise

[Jason Szumlanski]

I was highly against EG4 early on with their direct-to-consumer model, DIY
focus, and support model. But I have to admit that the handful of
installations of 18kPV and Wallmount batteries that I have done have gone
exceptionally well. I still get nervous about needing customer service to
update some settings remotely and some features not being available without
firmware updates, but overall, like Kevin wrote, they just work.

I am contemplating trying the Flexboss/Gridboss setup for on-grid jobs.

EG4 is doing something right. They can't be ignored. And their customer
service is going in the complete opposite direction from Sol-Ark. I feel
these days that the Sol-Ark tech support agents have disdain for installers
who dare to call and demand replacement of faulty components, and they have
no answers for when back-ordered parts will arrive (when they should
replace the whole inverter if they can't supply a repair part). If anyone
watches the YouTube videos with EG4's Showalter, you will see that they are
definitely targeting professional installers now and listening to feedback.
