Needs manual setup
Victron Energy Quattro 48/5000/70-100/100 120V + EG4 WallMount All Weather 280Ah
- Voltage matches: the 51.2 V battery suits this 48 V inverter.
- The battery maker says it works with this inverter's link (Victron BMS-Can), but the inverter maker doesn't list this battery. The battery maker doesn't say it can run without communication. Ask them before you set it up by hand.
Checked automatically against spec sheets. Not yet confirmed in a real install. Last checked 2026-10-12. We don't track firmware versions.
Size the battery cable and fuse for this pair in the build tool, from your run length.
What you'll set up yourself
- Ask EG4 whether this battery can run without communication. Their documents don't say.
-
Enter the battery's charge settings on the inverter by hand, in the battery
settings described in the inverter's manual.
- Max charge current: no more than 140 A per battery, from the battery's spec sheet.
- Charge voltage, float voltage, and low-voltage cutoff: from the EG4 WallMount All Weather 280Ah manual.
- Closed-loop communication needs an extra part: Victron GX device (e.g. Cerbo GX) for BMS-Can or a Lynx Smart BMS.

Values come from each maker's documents. "Not published" means the maker doesn't state it.
Confirm with the makers before you buy
- Each product's current limits. One or both aren't published, so ask both makers.
- Which firmware versions support this pairing. We don't track firmware.
- That your cable lugs fit the inverter's battery studs (M8) and the battery's terminals (Not published).
- How to install both safely, from each maker's manual and your local code.
This result checks two things: the battery's voltage suits the inverter, and the inverter maker lists this battery for closed-loop communication (the battery tells the inverter how to charge it). It doesn't check current limits, charge settings, firmware, cable sizes, or safe installation. Confirm those with both makers before you buy.
