Prices are approximate and vary by installer. The Sigenergy inverter price is included in the system cost above — you don't buy the inverter separately. Adding the Sigenergy EV car charger module is typically €500–€1,000 extra if not already included.
Sigenergy Gateway: What Does It Do?
The Sigenergy gateway is the communication hub of the SigenStor system. It connects the hybrid inverter, battery modules, and EV charger to your home Wi-Fi and the Sigenergy cloud platform.
System Monitoring
The gateway reports real-time data on solar generation, battery charge level, grid import/export, and EV charging status to the Sigenergy app on your phone.
AI Optimisation
The gateway runs the AI energy management algorithms, pulling weather forecasts and electricity tariff data to optimise when to charge, discharge, or export.
Firmware Updates
Over-the-air updates keep your system current with new features and performance improvements. The gateway handles all updates automatically.
The Sigenergy gateway is included with every SigenStor system — it is not sold separately. The gateway price in Ireland is bundled into the total system cost. It carries a 5-year warranty (shorter than the 10-year battery and inverter warranty).
Sigenergy App: Monitor & Control Your System
The Sigenergy app (available on iOS and Android) gives you full visibility and control over your SigenStor system from your phone.
What You Can See
- • Real-time solar generation (kW)
- • Battery charge level and state of health
- • Grid import/export in real time
- • EV charging session status and history
- • Daily, weekly, and monthly energy reports
- • Estimated savings and self-consumption ratio
What You Can Control
- • Switch between AI auto, self-consumption, or time-of-use modes
- • Set battery charge/discharge schedules
- • Start/stop EV charging remotely
- • Set EV charge limits and departure times
- • Enable/disable grid export
- • View and update firmware via gateway
AI Energy Management: How It Works for Irish Homes
Sigenergy's AI software automatically manages your energy to maximise savings. It learns your usage patterns and optimises based on:
Self-Consumption
Stores excess solar during the day and releases it in the evening when you need it. Maximises the amount of free solar electricity you use directly.
Time-of-Use Tariffs
In Ireland, smart meters enable time-of-use pricing. The AI charges from the grid when electricity is cheap (night rate) and uses stored energy during peak hours.
Export Management
Manages microgeneration export payments by deciding when to export surplus solar vs when to store it for later self-consumption.
Sigenergy vs Tesla Powerwall: Which Is Better?
| Feature | Sigenergy SigenStor | Tesla Powerwall 3 |
|---|---|---|
| Battery Capacity | 5kWh–48kWh (stackable) | 13.5kWh (fixed) |
| Expandable | Yes (add modules) | Limited (add units) |
| Built-in Inverter | Yes (up to 12kW) | Yes (11.5kW) |
| EV Charging | Built-in AC + DC, V2G | No (separate charger needed) |
| AI Management | Yes | Yes |
| Battery Chemistry | LFP | LFP |
| Warranty | 10 years | 10 years |
| Price (approx.) | €5,000–€10,000+ | €8,000–€10,000 |
Verdict: Sigenergy wins on flexibility (stackable capacity) and integrated EV charging. Tesla wins on brand recognition and proven track record. For Irish homes with EVs, Sigenergy's built-in V2G charging is a genuine differentiator.
Solis vs Sigenergy: Which Hybrid Inverter Is Better?
Solis and Sigenergy take very different approaches. Solis sells standalone hybrid inverters that pair with third-party batteries (Pylontech, Dyness, BYD). Sigenergy sells the SigenStor as one integrated inverter + battery + EV charger system. Here's how they compare for an Irish home install:
| Feature | Solis Hybrid | Sigenergy SigenStor |
|---|---|---|
| System Type | Inverter only — bring your own battery | All-in-one inverter + battery + EV charger |
| Battery Brand | Pylontech, Dyness, BYD, others | Sigenergy LFP only (5kWh / 8kWh modules) |
| Inverter Power | 3kW–10kW single-phase | 5kW / 8kW / 10kW / 12kW |
| EV Charging | No (separate charger needed) | Built-in AC + DC, V2G |
| AI Energy Management | Basic schedules | Yes — weather, tariff, usage |
| Inverter Warranty | 5 years (extendable to 10) | 10 years standard |
| Price (inverter only) | €1,200–€2,000 | Bundled — from €4,500 with 5kWh battery |
| Best For | Budget builds, mix-and-match batteries | One-stop premium install with EV |
Verdict: Solis is the cheaper, more flexible option if you already have (or want to choose) a separate battery brand. Sigenergy wins on integration, warranty length, and built-in EV charging — at a higher price point.
Sigenergy Hybrid Inverter: Models & Datasheets
The Sigenergy hybrid inverter is the brain of the SigenStor. Unlike standalone hybrid inverters, the Sigenergy unit is designed to connect directly to Sigenergy battery modules and the optional EV charger via the gateway.
