On my MotorHome I have generated 1.783Mw. We full-time.
Started with 800w array, added another 400w, reciently overpanel it to 600w, so we have 1400w of panels and 1140w of SCC throughput.
We just clicked our first Megawatt. We've got 4kW of PV split between two EG4 6500s that powered up November 8th 2022. 462.5 kWh on 2p1 and 571kWh on 2p2 totals to 1033.5 kWh! Woot Woot!
What are you doing for maintenance? 99.8% of my maintenance time is spent yakking on these forums ; -)
The other 0.2% is looking into anything I got an email on (my system sends me emails if it thinks anything is off).
Maint Issues:
1) I use 4 x Progressive ATSs like this - https://www.amazon.com/gp/product/B003VAWNVK/ref=ppx_yo_dt_b_search_asin_title
in my overall system. 2 of them went bad at year 4 (~3,000 switchovers) where the magnet/relay started 'sticking' and wouldn't close the contacts and had to replace them. I also had one of my Go-Power 120v@30a ATSs wiring melt - maybe bad twist nut connection.
2) One of my AIMS 12,000w inverters, with 4yrs / 25,000hrs of operation started putting out spurious voltages - and AIMS cannot supply any replacement boards. Had to pull it and replace it - trying a SUNGOLDPOWER 12,000w instead.
3) A butt-joint in a connection box installed by the original electrician burned up causing bad connection / weird things to happen for a few days. Had to find / fix.
This is what it looked like before burning up
4) Had a cheap relay I use to turn the inverters on/off by voltage 'stick' at year 4 and had to replace. Similar to the ATSs - no obvious failure it's just that the mechanical rocker started sticking for some reason.
This post prompted me to check my Midnite SCC, and after nearly 5 years off-grid we've produced 7.264 MWh. Doesn't really sound like much to me, but we don't lack any amenities and are 100% AC-driven (no 12v/24v appliances, etc...)
