Frequently Asked Questions
Does the MultiPlus-II 48V work with the Husky 2?
Yes. BigBattery lists this unit as compatible with 48V HUSKY 2 INV lithium battery systems, and the Husky 2 INV supports closed-loop communication. That means the inverter reads true state of charge from the battery's BMS rather than estimating from voltage.
What is PowerAssist on the MultiPlus?
PowerAssist lets the inverter supplement a limited AC supply with battery power. If a brief load exceeds what your shore or generator connection can deliver, the battery covers the difference instead of the breaker tripping. PowerControl works alongside it, capping how much incoming AC goes to charging.
Do I need a Cerbo GX with the MultiPlus-II?
No, the inverter works on its own. A Cerbo GX adds full remote monitoring and system control, letting you view and adjust the system from a phone or laptop. Most people add one once solar charge controllers and a battery bank are in the mix.
MultiPlus-II or EG4 6000XP: which one?
The MultiPlus-II 48/5000 is a 5,000VA inverter-charger with a 70A charger and no built-in solar input, so it needs a separate charge controller. The 6000XP is 6,000W with 8,000W of PV input built in. Choose Victron for ESS flexibility, EG4 for an all-in-one solar build.
What does the 70A charger mean in practice?
At 70A, a 5.12kWh 48V battery recharges from empty in roughly an hour and a half on shore power or generator, allowing for the taper near full. An external current sensor extends input management up to 100A for power-limited installations.
