More Solar, More Ways to Use It: Four lightweight 178W TOPCon solar panels combine with the Hoymiles HiBattery 1920 AC to create a flexible 710W solar and battery system. Ideal for sun-facing walls, façades, fences, sheds, garden offices and larger balconies where conventional rigid panels may be difficult to install.
Built for Sun-Facing Surfaces: With four flexible panels, Storm Plus 710W makes better use of larger south, south-east or south-west facing areas around your home. Each panel weighs just 3.5 kg, giving you substantial solar coverage without the weight of conventional rigid panels.
1.92 kWh Smart Energy Storage: Store available solar energy during the day and use it later when your household needs it. HiBattery supports self-consumption and time-of-use modes, helping you make more effective use of both solar generation and lower-cost electricity tariffs.
Intelligent Energy Management: The AC-coupled HiBattery delivers up to 96.5% bidirectional efficiency and 87% round-trip efficiency, while its LiFePO₄ cells are rated for 6,000+ cycles. Smart charging and discharging give you greater control over when your stored energy is used.
Smart Monitoring from Your Phone: Built-in Wi-Fi and Bluetooth connect the system to the S-Miles Home app, letting you monitor solar generation, battery status and energy settings from your phone.
Compact, Quiet and Outdoor Ready: Storm's TÜV-certified flexible panels offer IP67 protection, while the HiBattery provides IP66 protection, natural fanless cooling and operating noise below 17 dB(A).
Straightforward Installation: Mount the lightweight panels, connect them to the Hoymiles microinverter and position the HiBattery in a suitable location. Thunder provides a free one-to-one setup video call, with professional support available for the final AC connection.
Bundle and Save: Storm Plus 710W combines the complete Storm 710W solar system with 1.92 kWh of Hoymiles battery storage, saving £50 compared with purchasing the products separately.

FAQs
What is the Storm Plus 710W?
Storm Plus 710W combines four lightweight flexible solar panels, a Hoymiles microinverter and the 1.92 kWh HiBattery 1920 AC. It is designed for homes wanting greater solar generation together with smart energy storage.
What is the difference between Storm Plus 360W and Storm Plus 710W?
Both include the same 1.92 kWh HiBattery. Storm Plus 360W uses two solar panels and is particularly suited to balconies and smaller spaces. Storm Plus 710W uses four panels, making it better suited to larger sunny walls, façades, fences and outdoor areas with greater solar generation potential.
How much energy can the battery store?
The Hoymiles HiBattery provides 1.92 kWh of LiFePO₄ battery capacity and is rated for at least 6,000 charge cycles.
What happens to solar energy I don't use immediately?
Available energy can be stored in the battery for later use, helping you increase self-consumption rather than relying only on solar while the panels are actively generating.
Can the battery charge from the grid?
Yes. HiBattery supports time-of-use operation, allowing you to charge during lower-cost tariff periods and use stored electricity when grid prices are higher.
Where can I install the solar panels?
The four lightweight panels are particularly suited to sun-facing walls, façades, fences, sheds, garden offices and larger balconies. South-facing locations generally offer the strongest annual solar exposure, although south-east and south-west orientations can also perform well.
Can I monitor the system from my phone?
Yes. The S-Miles Home app works with the system's built-in Wi-Fi and Bluetooth, giving you access to solar production, battery status and energy management settings.
Does the battery require an electrician?
The flexible solar panels and microinverter are straightforward to assemble, while the complete battery system uses a professional final AC connection. Thunder can also help arrange installation support.
Can I expand the battery capacity later?
Yes. A second HiBattery 1920 AC can be added to increase total storage capacity to 3.84 kWh with the appropriate configuration.
Is the system suitable for outdoor use?
The Storm panels are IP67 rated and the HiBattery enclosure is IP66 rated. The battery should still be positioned according to Hoymiles installation guidance, including protection from direct sunlight and rainfall.

Annual consumption: 2,700 kWh (Ofgem typical medium household). Winter 60% / Summer 40%.
System: 4 x Storm 178W flexible solar panels (TopCon monocrystalline), total 0.71 kWp. Microinverter: Hoymiles HMS-800W-2T (800 VA, 2 MPPT, 96.7% peak efficiency).
Orientation: Modelled at 90-degree vertical mounting (typical for fence or balcony railing). This is a conservative estimate. Tilting panels to a more favourable angle will increase generation.
Year 1 generation: 525 kWh (estimated for London, based on typical balcony/fence mounting).
Panel degradation: 2% in year 1, 0.7%/year thereafter (conservative estimate for flexible ETFE panels).
Seasonal generation split: Winter 28% / Summer 72% (Thames region profile).
Self-consumption rate: 100% year-round. System output is well below household demand, so all generation is consumed on-site.
Electricity tariff: 30 p/kWh peak (average smart time-of-use daytime rate), 7 p/kWh off-peak (overnight rate), 3% annual inflation.
Battery: Hoymiles HiBattery 1920 AC (HB-1920-AC-SV), 1.92 kWh usable capacity, LiFePO4 cells, AC-coupled, 87% round-trip efficiency, IP66, 6,000+ cycle life, 10-year warranty.
Battery arbitrage: Off-peak grid charging at overnight rates, peak discharge during daytime. 365 days per year at full capacity (1.92 kWh). Solar generation is consumed directly by the household and does not charge the battery, leaving full battery capacity available for grid arbitrage year-round. Battery operates at 800W maximum output, sufficient to offset household base load during peak hours.
87% round-trip efficiency.
Battery arbitrage savings assume the customer is on a smart time-of-use tariff with off-peak overnight rates. Actual returns may be higher or lower than projected
depending on tariff availability and usage patterns. All figures are estimates based on the assumptions above and should not be considered as guaranteed
returns.
