Been setting up a similar combo for my garden office and this question keeps coming up so worth pinning down the specifics properly.
The EasyPlus 1600 is a combined inverter/charger — it handles AC charging from the mains (or a generator), but it has no built-in solar input. So yes, if you want panels involved, you absolutely need a separate MPPT controller. The EasyPlus itself won't accept DC from panels directly — that's a common misconception I've seen repeated a fair bit.
The way it actually works:
- MPPT controller takes input from your panels
- MPPT charges your battery bank
- EasyPlus draws from that same battery bank and handles the inverter/charger side
Victron do their own MPPT range which integrates nicely with the EasyPlus if you're using a VE.Direct or VE.Bus setup — the SmartSolar controllers are worth the money for the monitoring alone. That said, a Renogy or EPever MPPT will do the job fine if budget's tighter, you just lose the seamless integration.
Size your MPPT to match your panel array — don't just grab any old one. Check your panels' Voc carefully against the controller's maximum input voltage. Got this wrong first time round myself and had a slightly embarrassing moment.
Curious what battery chemistry you're running? Lead-acid, lithium? Changes the charge profile settings on the MPPT quite significantly.
Anyone else running an EasyPlus alongside solar for backup purposes rather than full off-grid? Would be interested to hear how others have set the charge priorities up.
