The midnight 250 isn't rated for 4kw of panels, but you should be seeing more than 2kw. I wonder if there is a limiter on the system somewhere.
I replied in the wrong place...sorryI don't think SCC is programmed according to how many watts of PV is connected. Maybe output amps is adjustable.
The Midnight Classic 250 used on these trailers can handle up to 250 Voc (plus tolerate higher with HyperVoc), but output is limited to 63A.
That should still be more than 2000W, even though it wouldn't reach 3950W below 62.7V output. And of course current accepted by battery drops off when you hit absorption and CV operation.
Your panels and their angles & insolation probably don't reach the power you are expecting.
What are the panel specs, and what is the series/parallel configuration?
What are all the readings from Midnight display?
so 2 x $2000 = $4000 for 2 invertersYou can buy Sunny Islands new on eBay, some listed for $2500 (including delivery) recently.
2400W of PV panels, maybe worth $0.20 to $0.50/W
Midnight Classic a few $hundred
Homeline breaker panel, enclosure around everything, trailer.
All assemble, a bonus if you use it that way.
Probably requires 1 ton truck to pull, try to get delivered.
I don't close the door, it's inside a shed. I paid a guy $50 for the Aluminum panel box and just haven't pulled the piano hinge pin yet. But the MS 250s run much better when not hot.That enclosure looks like it would prevent cooling air from reaching chargers, if closed.
Not good to hear that a Midnight Classic hurt itself with either available PV power or temperature.
The DC Solar boxes don't comply with SI specs for clearance, plus are enclosed except for whatever exhaust fans. Probably recirculates hot air rather than drawing fresh outside into the bottom of SI.
The box with electronics, about half that. Waterproof, but more crowded than recommended space for cooling.
I don't operate the (3) MS250s with the door closed, LOL, they do put out some heat. We bought a dozen of the DC Solar trailers are recondition them at our shop. Upgrades we can include are:That enclosure looks like it would prevent cooling air from reaching chargers, if closed.
