Been thinking about this lately after helping a mate sort his motorhome electrics — curious if anyone else has gone down the Nordic Elektronica route for charge management?
I've got a fairly straightforward setup on my own motorhome: Victron SmartShunt, a Fogstar 100Ah LiFePO4, and a decent B2B charger keeping things topped up from the alternator. Works a treat most of the time.
But the bit I keep going back and forth on is how fussy LiFePO4 can be when you're mixing charge sources — shore power, solar, and alternator all at once. Getting them to play nicely together without confusing the BMS is where it gets interesting.
Specifically wondering:
- Has anyone used a Nordic Elektronica smart charger alongside a Victron MPPT and found the communication between them reliable?
- Any gotchas when retrofitting into a European-built 'van (EuraMobil, Hymer, Bürstner etc.) where the factory wiring doesn't always match UK/German conventions cleanly?
I had a bit of a headache getting charge profiles to agree when I first switched from AGM — kept getting premature absorption cutoffs. Turned out the BMS was interpreting the charger's voltage spikes as a fault. Took a bit of fiddling with the charge parameters to settle it down.
Would be good to hear from anyone who's nailed a clean multi-source setup, especially if you're running a European 'van. Seems like there's more of us doing these retrofits than the forums sometimes suggest.
