Blue Sky 3024il
I added 520 watts of solar and a Bogart 30 amp system to my rig. It works well but a new problem has happened. It's now common for people to ask how we can have all these lights going and a big tv and...

I found the manual's limit deal
"Automatic current limit prevents output current from exceeding 40A with 12V batteries and 12V PV’s. If PV open circuit voltage (VOC) ever exceeds
30V which would occur with PV voltage greater than 12V nominal, current limit will become 30A until the 3024 reboots. Note that when the 3024 exits current
limit, it will briefly enter acceptance on it’s way back to MPPT even though battery voltage may be low."\\
So that doesn't apply here. if he is only seeing amps in the teens, did he hook up to the "load" terminals (limit of 20a) instead of the battery terminals?
He shouldn't do anything yet till what he has gets sorted out IMO. He may be ok, just set-up wrong?
2 140s =280/130 x 8.2 = 17.7a aimed at high sun, less flat --maybe 15a? That's with PWM so add maybe 8-9% for MPPT = 17a? (flat)
190/130 x 8.2 = 12a aimed at high sun so 10a flat? or 11a MPPT so should get about 28a with the two controllers
