Brilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.
Very very helpfuland so quick. Made sure that a non expert like myself understood what the problem was and how to resolve it.
Excellent response to diagnose a problem on our SolarEdge installation. Kept us informed at every step. Diagnosis quickly completed and solution implemented.
I’ve used Ron a couple of times regarding issues with my Givenergy inverter and batteries after Givenergy went bust. My system stopped working properly so it was a stressful time but Ron resolved the issues and got my system working properly again. He’s really helpful and knowledgeable and I wouldn’t hesitate to recommend him and to use him again if the need arose.
Thank you for your diligence. On this occasion the battery was able to be saved but they have given a route to hopefully arrange a repair from the manufacturer.
Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)
Safety Warning
Do not open your inverter or interfere with DC cabling. Solar panels produce live DC voltage whenever exposed to light. Always use your DC isolator switch and contact a qualified solar engineer for hands-on fault diagnosis.
Before you start: You need access to VRM (vrm.victronenergy.com) or VictronConnect (Bluetooth app). If you have neither, we can access VRM remotely during a diagnostic session — you just need to share VRM access or provide your installation ID.
MultiPlus charging faults are almost always configuration — not hardware. The charger section, AC input limit, DVCC settings, and BMS communication all interact. Work through these steps in order to isolate the cause.
Open VRM or connect via VictronConnect over Bluetooth. The MultiPlus device page shows the current charger state:
Also note the AC input power reading. If it shows 0W AC input, the MultiPlus is not receiving grid or generator power — that's a different problem (AC wiring, breaker, or grid relay fault).
VEConfigure controls the MultiPlus charger settings. The values must match your battery manufacturer's specifications exactly:
The most common mistake: float voltage set too high, so the MultiPlus never enters bulk mode because it thinks the battery is already charged. Or absorption set too low, so the battery never reaches full charge.
Remote VEConfigure access requires a Cerbo GX with internet and VRM two-way communication enabled. Without this, a VE.Bus to USB adapter and physical access are needed.
The MultiPlus limits how much current it draws from AC input (grid or generator). If this is set too low, all available power goes to AC loads — leaving nothing for charging:
The AC input current limit can be set in VEConfigure, VictronConnect, or on the VRM remote console under the MultiPlus device settings.
If your system has a Cerbo GX with DVCC (Distributed Voltage and Current Control) enabled, the BMS controls the MultiPlus charge behaviour dynamically. This is the most common hidden cause of charging failures:
Common BMS lockout triggers: low temperature (LiFePO4 batteries typically refuse charge below 0°C–5°C), cell overvoltage (one cell above safe limit), and communication timeout (BMS lost contact with GX device via CAN bus).
If BMS communication has dropped, check the CAN bus cable between battery and Cerbo GX. See our battery BMS disconnect guide for detailed CAN bus troubleshooting.
VE.Bus errors can lock the MultiPlus into a fault state where it refuses to charge until the error is manually cleared:
Firmware mismatch: If your system has multiple MultiPlus units (parallel or three-phase), all must run the same firmware version. A mismatch after a partial update is a common cause of VE.Bus communication errors. Update the GX device first, then all MultiPlus units together.
See our VE.Bus error codes guide for the full error code reference.
The Victron MultiPlus is an inverter-charger — it combines a mains inverter, a battery charger, and a transfer switch in one unit. Unlike simpler hybrid inverters that handle everything internally, the MultiPlus charger behaviour is controlled by a layered stack of settings: VEConfigure parameters, ESS assistant rules, DVCC limits from the BMS, and AC input current restrictions. When any one layer sends a conflicting signal — the charger stops. The hardware is almost always fine. The challenge is finding which layer is blocking the charge.
This is especially common in third-party battery integrations. Victron publishes compatibility lists and recommended settings for batteries like Pylontech, BYD, and Dyness, but installers frequently use slightly different parameters or forget to enable DVCC. Over time, firmware updates on either the Victron or battery side can change the BMS communication protocol, causing a previously-working system to stop charging. We see this pattern weekly — a system that worked fine for months suddenly stops after a firmware update or a seasonal temperature drop triggers the BMS low-temperature lockout.
