I have a newly installed ISC3042 installed in a Mercedes Sprinter Motorhome with a 150watt (so far) solar panel and a separate AGM 100a/h house battery connected to the Original start battery via a BEP Voltage Sensing Relay.

On paper this regulator looks good as an MPPT 30 amp with separate adjustable bulk and float voltage adjustments.

After considerable research I found that Jaycar are marketing an identical model (except the colour) as an MP3735

My ISC3042 regulator shut down with an E5 error after running for a long drive (5hrs) with the fridge as the only load and this code does not appear in the handbook.

When I stopped (the battery was fully charged and on float at 13.6v) the voltage then drifted up to 16v and E5 with the motor/alternator off, I think the fridge had cycled off so no load was present. (E5 cuts the load anyway)

Quite a mystery, but the supplier has contacted the distributor and confirmed the regulator has a problem, so is replacing all their shelf stock as well as mine.

I can't help but wonder if it has the same firmware problem as mentioned in another post on the ISC3022 in August.

Will post my progress,

Kevin
