High Voltage vs. Low Voltage

High-voltage storage (HV, 100–960 V) requires HV hybrid inverters (e.g., Solax, Goodwe ET, BYD HVS, Dyness Stack 100). Low-voltage (LV, ~48–51 V) for Victron, Sungrow SH-RS, Pylontech US series.

Brand Recommendation

For Goodwe ET: BYD HVS or Dyness Stack 100. For Solax: T-BAT HS series. For Fronius GEN24: Fronius Reserva. For Huawei: LUNA2000.

Frequently Asked Questions
Which storage fits my inverter?

Brand-specific: Goodwe ET → BYD/Dyness, Solax → T-BAT, Fronius → Reserva, Huawei → LUNA. We are happy to check this for your system.

How large should the storage be?

Rule of thumb: 1–1.5 kWh storage per 1 kWp PV output. For 8 kWp, this means 8–12 kWh storage.

LFP or NMC?

For home use, definitely LFP – safer, more durable, more fire-resistant. NMC only in special applications.

Eligible for funding?

Yes, in Austria via the EAG Investment Grant for Electricity Storage.

Lifespan?

LFP storage 6,000–10,000 full cycles (~16 years). 10-year warranty standard.

Delivery?

Freight forwarder with curbside delivery.
