Domestic solar panels for a vehicle

I picked up one of those 75/15 controllers on special the other week for $85

yet to hook it up but they have a good rap...

going to replace the $15 unit that i put on the van when we bought it.... (which has been working just fine btw)

[biggrin]

is the MC4 better than the Anderson plug? (just the normal Anderson but the power-pole)

Cheers

I have an MC4 connecting the 80 watt panel on the roof rack of the Defender to the starting battery and it works fine. Smaller than an Anderson plug. I wrapped mine in insulation tape for extra sealing.
The cheap regulators seem to limit the panel output to protect the battery from being overcharged, so adding a bigger panel may not automatically increase the charge going to the battery. Does the Victron unit adjust the charging rate to the charging capacity of the battery?
It might also be an idea to check the maximum safe charging rate of the battery to avoid overcharging it.
Domestic panels might have a heavier frame than auto ones.
