Latest MOAN Specs

Hey everyone, I built one of the first MOANs, but given I’ve been away for a few years, I thought I’d check in and see if there are new supplies that folks recommend use in building these?

I just dusted off the OG, and am interested in spending some time upgrading it if there are some recommended enhancements (e.g. better solar panel, recommended battery, etc).

Appreciate any tips!
