SolaX X1-FIT AC Chargers G4 (Single Phase)
The SolaX X1-FIT G4 AC Charger is a high-efficiency, single-phase AC-coupled battery inverter designed for retrofitting energy storage to existing solar PV systems or adding smart battery storage to new installations. Ac charger available in sizes from 3.7kW to 7.5kW, it delivers flexible, intelligent energy management for homes and small businesses.
Key Features
- Available sizes: 3.7kW, 5.0kW, 7.5kW
- Up to 110% AC overload output (on-grid); up to 120% overload output off-grid (for 1 hour)
- Maximum charging/discharging efficiency: 97%
- Store surplus solar or off-peak grid energy in batteries
- Switchover time <10ms for backup (EPS) operation
- 150% EPS output for 10 seconds
- Supports both lithium-ion and lead-acid batteries
- CT compatible for fast load response (within 0.3s)
- Intelligent load management (e.g. heat pump, EV charger)
- On- and off-grid parallel function, up to 150kW
- 5 work modes and 2 programmable charging periods
- Quick configuration with U-disk (USB drive)
- IP65 protection for indoor/outdoor installation
- Integrated Type II SPD (AC & DC)
- VPP-ready (Virtual Power Plant) and ancillary services support
- Remote monitoring and control via WiFi/app
Technical Specifications
- Nominal output power: 3.7kW, 4.6kW, 5.0kW, 6.0kW, 7.5kW
- Battery voltage range: 40–60V (model dependent)
- Max. continuous charge/discharge current: up to 50A (model dependent)
- Switch time (EPS): <10ms
- Operating temperature range: -35°C to +60°C (derating above +45°C)
- Max. operation altitude: 3000m
- IP rating: IP65
- Typical noise emission: <30dB
- Cooling: Natural convection (fanless)
- Communication: WiFi, RS485, CAN, U-disk, CT
- Warranty: 10 years
- Certification: G98, G99, VDE4105, CEI 0-21, EN50549, AS4777, IEC62109, and more
Operating Modes
- Self-use (default): Prioritises powering local loads from the battery, then grid
- Feed-in priority: Maximises export to grid before charging battery or supplying loads
- Force time use: User-defined charging/discharging periods for tariff optimisation
- Backup mode: Maintains battery for backup, only discharges during grid outage
- Peak shaving: Reduces grid consumption during peak periods
Applications
- Retrofitting battery storage to existing solar PV systems
- New solar-plus-storage installations
- Smart home energy management and backup
- Participation in VPP and grid services
