Can I use a third-party battery with a Sungrow or GoodWe inverter?

Generally no. Sungrow closes the loop only with its own SBR/SBH batteries. GoodWe runs an approved list, often its own partners such as BYD or Pylontech, so a third-party 48V LFP pack works only if it is on that list. Ours is not. If you want the freedom to choose and change your battery, pick an open hybrid inverter.

What does "battery-agnostic" actually mean?

It means the inverter exposes a standard CAN or RS485 protocol, so any battery whose BMS speaks that protocol can close the loop with it - no approved-list gatekeeping. Open inverters like Deye and Sol-Ark are battery-agnostic, while Solis maintains a broad supported list that works the same way in practice. That is what lets you mix brands, expand later, or switch suppliers without replacing the inverter.

Savolture / Inverter Compatibility

One 48V LFP Battery. Many Open Inverters.

Q: Which inverters are compatible with a 48V LFP battery?

Open hybrid inverters are battery-agnostic and close the loop with a compliant 48V (51.2V) LFP pack over CAN/RS485 - Deye, Sol-Ark, Solis, Growatt and LuxPower among them. Restricted platforms like Sungrow and GoodWe only run their own or approved batteries, and Fronius and Victron vary by model. Always confirm the closed-loop pairing for your exact inverter model and firmware before buying.

Q: What is the difference between open-loop and closed-loop communication?

In closed-loop, the battery BMS and inverter exchange live data such as state of charge, temperature, and current limits over CAN/RS485, and the inverter obeys the BMS. In open-loop, there is no data link, so the inverter estimates the battery state from voltage alone. Open-loop charges the battery but drops the BMS coordination and usually voids the pairing warranty, so it is treated as a fallback, not a setup option.

Q: Does Deye or Sol-Ark work with any 48V battery?

Both are open, battery-agnostic platforms and close the loop with a compliant 48V LFP pack over CAN/RS485, provided the correct battery protocol profile is selected in the inverter menu. They are among the most common pairings we confirm. We still verify the exact model and firmware, because protocol support can shift between firmware versions.

Q: How do I confirm my inverter and battery will work together?

Send us your inverter make, model, and firmware version. We confirm the closed-loop pairing - the protocol profile, cable and pinout, and settings - before you order, so compatibility is verified up front rather than discovered on install day.

Compatibility is decided by the inverter ecosystem. Open hybrid inverters close-loop over CAN / RS485; closed platforms lock the battery choice.

The most expensive mistake in a home storage build is not picking the wrong battery. It is pairing a battery with an inverter that will never talk to it. A 48V LFP pack can be perfect on paper and still throw a communication fault because the inverter only closes the loop with batteries on its own approved list.

Quick answer: Open hybrid inverters — Deye, Sol-Ark, Solis, Growatt, and LuxPower — are battery-agnostic over CAN or RS485. Closed platforms — Sungrow and GoodWe — only close-loop with their own or approved batteries. Fronius and Victron vary by model.

Open vs closed decides the project before the battery does.

Make the core distinction visible before the long compatibility matrix.

Every hybrid inverter has to talk to the battery: state of charge, charge and discharge limits, and battery temperature. That conversation is the difference between a system that simply works and one that is rejected on install day.

Open inverters support standard communication over CAN bus or RS485, so a compliant BMS can join the conversation. Closed inverters only run closed-loop with batteries on their own approved list.

If you have not yet chosen your architecture, see the upstream guide to low voltage vs high voltage home batteries.

Installer note: spec an open inverter when battery freedom matters. It keeps the battery choice flexible without forcing the project into a single closed ecosystem.

Open inverter ecosystem with one battery serving many inverters versus a closed ecosystem locked to one approved battery — Open inverter ecosystems preserve battery choice; closed ecosystems restrict it.

How closed-loop communication actually works

Keep the technical proof close to the compatibility claim.

Closed-loop data exchange between a 48V battery BMS and a hybrid inverter over CAN and RS485 — Closed-loop operation depends on cable, protocol, and profile matching.

Compatible means the battery BMS and inverter exchange live data continuously: state of charge, temperature, voltage, and charge/discharge current limits.

The physical layer, the protocol, and the selected inverter battery profile all need to line up. Miss one of those and the system falls back to voltage control or faults during commissioning.

For setup detail, see the 48V hybrid inverter battery pairing guide.

Frequently asked questions

Six schema questions, made easier to scan.

Which inverters are compatible with a 48V LFP battery?

Deye, Sol-Ark, Solis, Growatt, and LuxPower are the primary open paths for compliant 48V LFP packs.

Can I use a third-party battery with Sungrow or GoodWe?

Sungrow is closed. GoodWe depends on an approved list, so exact model confirmation matters.

What does battery-agnostic mean?

The inverter can communicate with compliant batteries through an open protocol rather than a single locked battery family.

What is the difference between open-loop and closed-loop communication?

Closed-loop shares live BMS data. Open-loop guesses from voltage and should be treated as a fallback.

Does Deye or Sol-Ark work with any 48V battery?

They work with compliant BMS profiles, but exact model settings still need confirmation.

How do I confirm my inverter and battery will work together?

Check inverter model, firmware, protocol profile, cable, and pinout before ordering.
