The Growatt SPF 5000 ES is a popular 5kW, 48V off-grid solar inverter designed for residential backup and self-consumption, capable of working with or without batteries. It is a single-phase inverter with a built-in MPPT charge controller, commonly used for creating independent power systems.
-
- Power Capacity: 5000W rated power (5kVA), capable of managing 150% nominal power for surges (up to 10,000VA surge power).
- Battery Voltage: 48VDC (supports Lithium and Lead-Acid).
- Solar Input: Maximum PV Array Power of 6000W, with an MPPT voltage range of 120VDC–430VDC.
- Efficiency: Peak efficiency is 93%.
- Grid/Generator Input: Can accept AC input from the grid or a generator to charge batteries.
- Operation Modes: Functions as an all-in-one system with integrated UPS functionality, featuring a transfer time of 10-20ms.
- Parallel Capability: Can operate in parallel for capacity expansion up to 30kW (up to 6 units).
- Monitoring: Supports WiFi or GPRS remote monitoring via the ShineWiFi-F module.
-
- Battery-Optional: Can operate directly from solar power during the day, even if a battery is not connected.
- High PV Input: Supports up to (6000text{Wp}) of solar panels, allowing for higher energy generation in low-light conditions.
- Easy Expansion: Modular design allows for simple parallel stacking of up to 6 inverters (30kW total).
- Compatibility: Works with lithium-ion batteries and supports communication with Growatt ARK and GBLI battery models.
-
- Standby Consumption: The unit has a relatively high idle power consumption, often noted around 70W per hour.
- Not for Grid-Tie: This is an off-grid inverter and cannot feed power back into the national grid.
- Monitoring Limits: The app and cloud monitoring data might have a 5-minute delay.
-
- Battery Selection: Ensure the correct battery type is selected in Program 5, and set protocol L51 for Growatt lithium batteries.
- Maintenance: Ensure the installation area allows for proper cooling, as it is a high-frequency inverter.
