The €600 battery grant explained
You can apply with or without solar panels. Our “grant loophole” reel explains the difference, including when a BER is needed.
For eligible home battery installations of 5kWh or more. Receive SEAI approval before installation and use an SEAI registered Solar PV Contractor. A post-works BER is required where solar PV is present. Other scheme conditions apply.

Made for homes without solar panels
No Solar Panels Required
This hybrid system stores grid electricity. You do not need a PV array or plans to install one. The hybrid inverter also has two MPPT inputs for future solar panels, which are not included.
16.07kWh Dyness Battery Storage
1 low-voltage LFP battery pack with 15.27kWh total manufacturer-stated usable battery energy, an IP65 enclosure and WiFi/app monitoring.
5kW Solis Charger/Inverter
Charges the battery from the grid and converts stored battery energy into electricity for your home.
Automated Time-of-Use Charging
Your REC configures charging around your cheap tariff window. 2AM–6AM is an example, not a requirement.
Automatic Daytime Supply
The battery supplies household demand within the inverter's output limit. Any extra demand is supplied by the grid.
Standard NC6 Admin Included
SolarBoss prepares and handles the standard NC6 paperwork for this package. Electrical installation remains separate.
An illustrative example, built around your usage
What Could NightSaver 16 Save You?
Selected: 16.07kWh Dyness storage (15.27kWh usable). Equipment: €3,749.00 incl. VAT; installation and delivery extra.
Example tariffs of 8.5c/kWh at night and 35c/kWh during the day. Approximately one full useful battery cycle every day, with conversion losses and battery degradation included.
Illustrative equipment payback
Assumes the selected battery capacity can be charged and used in full every day under the example tariffs.

15-year estimated net benefit
Installation excluded. Savings are illustrative, not guaranteed. Net benefits subtract the selected equipment price, before delivery, installation, maintenance, replacement or finance costs.

See the assumptions and calculation
Selected usable battery energy when new: 15.27kWh. Each selected battery provides 15.27kWh manufacturer-stated usable energy. The model assumes 93.9% AC-to-battery charging efficiency and 93.8% battery discharge efficiency, using the Solis published maximum figures as illustrative assumptions, not guaranteed operating efficiencies. Conversion losses reduce the energy delivered to your home and increase the grid electricity needed to charge the batteries.
Annual savings = usable battery energy × (day rate × discharge efficiency − night rate ÷ charge efficiency) × 365 × average modelled capacity. The model uses an illustrative assumption of 70% remaining capacity after 8,000 equivalent full cycles; this is not a warranty or a prediction of the selected battery’s service life. It models degradation linearly for illustration; actual degradation may differ. At one equivalent full cycle per day, 15 years is approximately 5,475 cycles, with about 79.5% capacity at the end of year 15 and about 80.2% average during that year.
Tariffs stay fixed in this illustration; there is no export payment, standing-charge saving, inflation, battery replacement, delivery, installation or financing allowance. Not every home can charge or use a full useful cycle each day. Consider your daytime consumption, cheap-rate window, household demand and charging limits.

Paperwork taken care of
SolarBoss handles the NC6 administration
Standard NC6 paperwork/admin is included in the advertised package price. SolarBoss prepares and handles the standard notification using the accurate information and technical documents you and your REC provide.
- Supply your correct MPRN, installation address, Eircode and required account information.
- Your REC must confirm site suitability, compatibility, installation design and required type-test/grid compliance documents.
- Any technical confirmation, declaration or signature required from the customer or REC must come from that party. SolarBoss does not sign an electrician's declaration on their behalf.
- The ESB Networks process must be completed before connection. The standard process requires that ESB Networks receives the NC6 and does not object within 20 business days.
Existing generation or site circumstances can affect eligibility for the standard process. Your REC must confirm the appropriate connection route. ESB Networks connection guidance →
Your questions, answered
Can I use this without solar panels?
Yes. It is an hybrid battery system that charges from the grid. No solar panels or PV installation are required for the night-rate use described here.
Will it cover all my daytime electricity?
It depends on your usage. The selected package has 15.27kWh usable battery energy before conversion losses. The inverter supplies up to 5kW rated output; the grid supplies demand above that limit or when stored energy is exhausted.
Are the example savings guaranteed?
No. The example assumes a full useful cycle every day at 8.5c/kWh night and 35c/kWh day, with conversion losses and modelled degradation. Lower utilisation, different rates or additional costs will change the result.
Does the price include installation?
No. €3,047.97 + VAT (€3,749.00 incl. VAT) covers the selected equipment and standard SolarBoss NC6 paperwork/admin. Electrical installation and site-specific work cost extra. Delivery is calculated at checkout for the selected pack and fulfilment locations.
What happens during a power cut?
The hybrid inverter has a backup output, but backup circuits require separate REC design, wiring and commissioning. Whole-home backup installation is not included in this equipment package.
Do I need a particular electricity tariff?
You need a tariff with a sufficiently low charging rate compared with the daytime electricity you avoid, after allowing for conversion losses. Check your provider's rates, cheap-rate times and any tariff conditions.
