Growatt SPF 5000 ES Lite 5kW Off-Grid Inverter

Growatt SPF 5000 ES Lite 5kW Off-Grid Inverter

The Growatt SPF 5000 ES Lite 5kW Off-Grid Inverter is a practical solar power and backup solution for homes, offices and small businesses. It combines a 5000W pure sine wave inverter, an integrated MPPT solar charge controller and flexible battery compatibility in one compact unit.

The inverter is designed for customers who want to reduce grid dependence, improve load shedding protection or build an off-grid solar system. It can operate with a suitable 48V battery bank or run without batteries where the system is configured accordingly.

Main Benefit

The main advantage of the Growatt SPF 5000 ES Lite is its flexible energy management. The inverter can prioritise solar power, use grid electricity when required and charge a connected battery bank for backup power during electricity interruptions.

When solar production is not sufficient to supply the connected loads, the inverter can combine available solar energy with grid power. This helps customers make better use of their solar panels while maintaining a stable power supply.

Off-Grid Inverter Technology

The Growatt SPF 5000 ES Lite is an off-grid inverter designed for battery backup and solar energy storage systems. It produces a pure sine wave AC output, making it suitable for many household appliances, office devices and essential electrical loads.

The inverter has a rated output power of 5000W and a surge capacity of up to 10000VA. The additional surge capacity helps accommodate the temporary start-up requirements of certain appliances and equipment, provided the overall system is correctly sized.

Benefits

• Rated inverter output of 5000W.
• Pure sine wave AC output.
• Surge capacity of up to 10000VA.
• Compatible with 48V lithium-ion and lead-acid batteries.
• Can operate with or without batteries.
• Integrated MPPT solar charge controller.
• Supports up to 6000W of solar panel input.
• Wide 120VDC to 450VDC MPPT operating voltage range.
• Maximum PV open-circuit voltage of 500VDC.
• Maximum solar charging current of up to 100A.
• Configurable solar or grid input priority.
• Optional WiFi or GPRS remote monitoring.
• Parallel expansion capability for larger systems.
• Compact wall-mounted design.

Solar Panel Compatibility

The Growatt SPF 5000 ES Lite supports a maximum solar panel array size of up to 6000W. The integrated MPPT solar charge controller operates within a voltage range of 120VDC to 450VDC and supports a maximum PV open-circuit voltage of 500VDC.

The inverter includes one MPPT tracker with one solar input string and supports a maximum PV input current of 22A. Correct solar panel string sizing remains essential to ensure that the voltage and current stay within the inverter operating limits.

Battery Compatibility

The Growatt SPF 5000 ES Lite supports compatible 48V lithium-ion and lead-acid battery systems. Battery capacity should be selected according to the required backup time, connected appliance loads and expected solar generation.

The inverter supports a maximum solar charging current of up to 100A and an AC charging current of up to 80A. Correct battery settings remain important to protect the battery bank and ensure reliable long-term system operation.

Works With or Without Batteries

The Growatt SPF 5000 ES Lite can operate with or without a battery bank. This gives customers the flexibility to install a solar solution in stages or use solar and grid power to supply loads during the day.

A compatible lithium battery bank is recommended for customers who require reliable backup power during load shedding or electricity interruptions. Operating without batteries limits the backup capability when both solar production and grid power are unavailable.

Grid and Solar Power Management

The inverter allows customers to configure solar or grid input priority according to their energy requirements. Solar power can be prioritised to reduce electricity usage from the grid, while grid power can assist when solar generation is insufficient.

The inverter also allows flexible scheduling of charging and discharging times, providing additional control over how the battery bank is used during different periods of the day.

Parallel Expansion

The Growatt SPF 5000 ES Lite supports parallel operation for customers who need a larger off-grid solar system. Up to 9 compatible inverter units can be connected in parallel, allowing expansion to a combined capacity of up to 45kW.

Parallel systems require correct design, compatible equipment and professional installation. The solar panel array, battery storage capacity, cabling and protection equipment must be sized according to the total system requirements.

Monitoring

The Growatt SPF 5000 ES Lite supports optional WiFi or GPRS remote monitoring. When the suitable monitoring accessory is installed, customers can view important system information and monitor inverter performance remotely.

Performance

The Growatt SPF 5000 ES Lite delivers a rated output of 5000W with peak efficiency of up to 93%. The inverter provides a 230VAC output with pure sine wave power suitable for many common residential and business appliances.

The inverter has a typical transfer time of 10ms and a maximum transfer time of 20ms. The actual suitability for sensitive equipment should be assessed according to the equipment requirements and the complete electrical system design.

Applications

• Residential load shedding backup systems.
• Off-grid homes and cottages.
• Small business backup power systems.
• Office backup power installations.
• Solar battery storage systems.
• Essential appliance backup systems.
• Farmhouses and remote properties.
• Grid-assisted solar systems.
