Needs manual setup
Growatt SPF 12000T DVM-MPV + SimpliPhi Power PHI-3.8-48-60
- Voltage matches: the 51.2 V battery suits this 48 V inverter.
- The inverter maker doesn't list this battery for closed-loop communication. The battery maker says it can run without communication, so you enter its charge settings on the inverter 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
-
Enter the battery's charge settings on the inverter by hand, in the battery

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 (Not published) and the battery's terminals (3/8 IN (10 mm)).
- 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.
