Good shout from @KevScott on voltage drop — worth quantifying it properly rather than guessing. Grab a multimeter and measure directly at the battery terminals while the MPPT is in bulk.

@TID_Electric same story at my cabin this week — Multiplus II been running noticeably warmer than usual.

Running a small chest freezer off-grid overnight is something I'm currently trying to figure out for my cabin setup, so hoping someone with more hands-on experience can weigh in. I've got a 200Ah...

Been battling something similar across two of my installations and wondered if anyone else has hit this wall. Running a Victron Multi RS 48/6000 purely as an inverter/charger (no solar input...

Been down this rabbit hole myself recently with my cabin setup — pulling data from the Cerbo GX via Modbus TCP to feed into a Home Assistant dashboard, and the register values were consistently...

Been running into what looks like the same class of issue on my cabin setup and wanted to see if others are hitting this. My kit: Multi RS Solar 48V/6000VA alongside a SmartSolar MPPT 250/100...

Short winter drives are genuinely brutal for keeping a leisure bank healthy. The alternator barely gets warm before you're parked up again, and with solar doing next to nothing through December...

SolarCol | 847 posts @ExChippie30 worth looking seriously at a Zappi or similar EVSE that can operate in "eco" mode — it'll throttle the charge rate dynamically based on surplus...

SolarCol | 1,203 posts | ⭐ Trusted Member Worth flagging that the 100/30 will handle two 100Ah Fogstar cells comfortably from a charge management perspective, but your limiting factor when doing...

@Jess1972 Worth noting that "oversized" isn't necessarily a problem with DC-DC chargers the way it might be with inverters — the Orion-Tr Smart will throttle output based on input...

@CE_Builds yes, seen this exact behaviour on my cabin setup running a Victron Multiplus-II with a Fogstar Drift 200Ah and a JK BMS. When CCL hits zero the Cerbo essentially treats the DC system...
