Warranty and compliance

Panel warranty: 25 years
Panel performance warranty: 87.4% min. after 30 years
Inverter warranty: 10 years
ENA register: No entry matched

Notes from our research: Not itself on the ENA register: Thunder says the solar side is based on the ENA-listed Bolt configuration, but the UK plug-in framework does not extend to plug-in battery systems, so the battery connection is hard-wired professionally. Battery: 1.92 kWh LiFePO4, >=6,000 cycles, up to 1,000 VA charge/discharge, 800 VA nominal on-grid output, round-trip efficiency up to 87%, 460 x 240 x 203 mm, 24 kg, IP66, 10-year warranty. Microinverter and panel specs are the same as the Bolt kit; inverter warranty (10 years), temp coefficient, frame and glass details come from the Bolt datasheet rather than the Bolt Plus page. Optional extras: 10 m AC cable, battery mounting set, flat roof mounting upgrade, installation. Upgradeable to 920 Wp with a second panel. Microinverter: recommended module power 320-540 W+ per input (no hard max W per channel given), max input 65 V, start 22 V, max short-circuit current 2 x 25 A, MPPT efficiency 99.8%, galvanically isolated HF transformer, 261 x 180 x 35.1 mm. Panel: power tolerance 0/+5 W, 1500 V DC max system voltage, 5400/4000 Pa load. Datasheet says 'dual glass' but does not state bifacial, so bifacial left null. Panel performance: max 1% first-year, 0.4%/yr thereafter. Datasheet notes DNO notification under G98 still applies. The monitoring app is S-Miles Home (the Hoymiles app), suggesting a Hoymiles-built inverter, but Thunder does not name the OEM.
