How the Axle VPP works with your Solis inverter
Axle links thousands of home batteries into one virtual power plant. When the grid needs power, they export together and you get paid.

Export during grid events
You get paid
How much can you earn?
We pay £1/kWh for every unit your battery exports during a grid event, and at least £10 a month even when the grid is quiet.
Events depend on grid conditions in your area, so earnings vary month to month. Payments stack on top of any export tariff you already have.
Millions paid out to battery owners
Here's what a few of them say.
SolaX owner“Axle has been a game changer for me. Where else can you get paid £1 per kWh during grid events. A guaranteed £10 per month. And you don't even need to change supplier! We asked for more events and you've delivered on that front too. Keep up the great work Axle team.”
Sigenergy owner“Been with Axle a couple of months now. Sigenergy battery system. Usually make around £8.50 per event which is usually 1 hour. … Axle take control of my battery during the event & after they switch it back to my normal program. Great way to increase our ROI. Seamless & hassle free. Money is in the account 72 hours after the event.”
SolarEdge owner“I love being part of Axle! It's great to help balance the grid and reduce the need to fire up dirty power stations when demand is high, and getting paid for doing it is a very nice bonus! The whole experience has been excellent too: payments are quick and straightforward, the website is easy to use, and whenever I've needed help their customer support team has been fast and helpful.”
Is your Solis system compatible with Axle?
Axle works with Solis hybrid and AC-coupled inverters on SolisCloud, single or three-phase, with whichever battery they're paired with. Grid-tied Solis inverters have no battery, so they can't join.
Compatible Solis inverters include
- S6 single-phase hybrids: S6-EH1P(3-10)K-L-PLUS, the earlier S6-EH1P(3-8)K-L-PRO and S6-EH1P(3-6)K-L, and the S7-EH1P(8-12)K02-NV-YD-L
- Fifth-generation single-phase hybrids: S5-EH1P(3-6)K-L and RHI-(3-6)K-48ES-5G
- Three-phase hybrids: S6-EH3P(5-12)K-H, S6-EH3P(8-18)K02-NV-YD-L and S6-EH3P(15-20)K-H, plus the RHI-3P(5-10)K-HVES-5G
- AC-coupled: S6-EA1P(3.6-6)K-L and S5-EA1P3K-L single-phase, and the S6-EA3P(5-10)KAA-NV-YD-H-PRO three-phase
