Solis Battery Ireland (2026): IntelliHome, FlexAIO and the Best Batteries for Solis Inverters

Quick answer: Solis now makes its own home batteries. The IntelliHome range (5.1, 10.2 and 16kWh LiFePO4 modules) pairs with Solis S5 and S6 low-voltage hybrid inverters, and the new FlexAIO is an all-in-one inverter and battery system. Many Irish homes with a Solis inverter also run a third-party battery such as Dyness. Here’s how to choose the right Solis battery setup in Ireland.

Solis battery options in 2026

Solis says its new residential battery lines support 90% depth of discharge and over 6,000 cycles. FlexAIO launched in the UK first, with pre-orders from 30 September 2026, so check Irish availability with your installer.

Which Solis inverter works with a battery?

Not every Solis inverter can take a battery. The S6-GR1P range is a standard grid-tied (string) inverter with no battery connection. For storage you need a hybrid such as the S6-EH1P L-PLUS (3 to 10kW single-phase, for 40 to 60V low-voltage batteries), or an AC-coupled battery inverter to add storage to an existing solar system. Read our full Solis S6 hybrid inverter review.

Already have Solis solar without a battery?

You have two routes:

• Swap to a Solis hybrid and add a battery: the cleanest option if your inverter is older.
• Add an AC-coupled battery inverter (such as the Solis S6-EA1P) alongside your existing inverter: no need to touch your current solar setup.

Either way, a battery of 5kWh or more fitted by an SEAI-registered installer can qualify for the €600 SEAI battery grant, even if you already have panels.

Will a Solis battery work in a power cut?

Only if the system is set up for it. Solis hybrids have a backup (EPS) output that must be wired to a backup circuit, and FlexAIO has built-in whole-home backup switching. Many Irish installs skip this to save money, so ask before you sign. See will your solar battery work in a power cut?

Things to check before you buy

• Compatibility: Solis says inverter and battery pairings vary by market, so confirm the exact pairing approved for Ireland.
• ESB Networks connection: single-phase homes normally connect under NC6 for up to 6kW of export. A 10kW single-phase hybrid needs export limiting or extra approval.
• Warranty and support: buy through an installer who registers the warranty and supports you locally.

Solis vs other batteries

Solis is a solid value choice, especially if you already have a Solis inverter. If you want a premium all-in-one, we recommend Sigenergy SigenStor. For a value all-in-one, see the GoodWe ESA review, and for a proven third-party battery, the Dyness 10kW review.

Frequently asked questions

Does Solis make its own battery?

Yes. Solis launched its IntelliHome battery range and the FlexAIO all-in-one system in 2026. Before that, Solis hybrids were usually paired with third-party batteries.

What size Solis battery do I need?

For most Irish homes, 5 to 10kWh covers the evening and overnight. Homes with an EV or heat pump often go bigger. We size it from your bills at the free survey.

Can I add a battery to my existing Solis inverter?

If it’s a Solis hybrid, yes. If it’s a grid-tied S6-GR1P, you’ll need an AC-coupled battery inverter or a hybrid upgrade.

Is there a grant for a Solis battery?

Yes. A battery of 5kWh or more installed by an SEAI-registered installer can get the €600 SEAI battery grant.
