Victron questions, answered

Is the 150/45 a bigger MPPT than the 100/50?

Not on a 12V battery. Victron rates the 100/50 at 50A and up to 700W of panel at 12V, the 150/45 at 45A and 650W. The 150 adds input voltage for longer series strings and works on 48V banks.

Which MultiPlus-II for a 30A or 50A RV?

The 120V models take one 120V supply, the usual fit for a 30A rig. The 2x120V models accept 120/240V split-phase shore power for a 50A rig. The first number in the name (12, 24 or 48) must match your battery bank.

Do I need a DC-DC charger for a lithium house battery?

Victron says the alternator must be protected from overload. Its Lithium NG manual asks for an alternator rated at least twice the battery's Ah, a temperature-controlled regulator and a current-limiting device such as a DC-DC charger. The SuperPack NG manual says to fit a DC-DC charger and names the Orion-Tr Smart and Orion XS.

What size SmartShunt do I need?

Size it to current. A 12V MultiPlus-II 12/3000 draws roughly 215A continuous by our estimate (2,400W at 93% efficiency), so a 500A SmartShunt suits most single-inverter RVs. Battery capacity is just a setting, from 1 to 9,999Ah.

Do Lynx modules come with fuses?

No. The Lynx Distributor takes MEGA fuses and the Lynx Class-T Power In takes two Class-T fuses, all sold separately. Build on M10: M8 and M10 modules cannot be joined.

Can you check my Victron parts list?

Yes. Start with the RV solar and battery calculator, or book a power-system consultation and our Victron-trained team will go through the controller, inverter, battery monitor and fusing with you.
