Detailed description
Growatt SPF 3500 ES 3.5kW Off-Grid Solar Inverter
The Growatt SPF 3500 ES 3.5kW 48V Solar Inverter is designed for off-grid solar power applications where dependable AC output and battery-based energy storage are required. With a rated output of 3500W, this inverter can be considered for residential and small-business solar systems that need to operate compatible electrical appliances within the inverter's power limits.
Its specifications include a 48V DC battery system, 230V AC output, pure sine wave waveform, and 93% peak efficiency. These features make it a suitable option to evaluate for backup power installations and off-grid solar projects.
3500W Rated Power for Everyday Applications
The Growatt SPF 3500 ES has a rated power of 3500VA / 3500W. The actual appliances it can operate simultaneously depend on their combined running wattage, power factor, and starting surge requirements.
Before installation, calculate the total load of appliances such as fans, lights, televisions, computers, routers, and other equipment. Motors, refrigerators, pumps, and compressors may require additional starting power, so their surge requirements should be checked carefully.
48V DC Battery System
This inverter uses a 48V DC battery system. Selecting a compatible battery bank is essential for stable operation and suitable backup duration.
Battery capacity should be determined based on the connected load, desired backup time, usable battery capacity, and conversion losses. Battery compatibility and supported charging parameters should be confirmed from the official Growatt SPF 3500 ES datasheet before purchasing a battery.
Pure Sine Wave AC Output
The Growatt SPF 3500 ES provides pure sine wave output with a nominal AC voltage of 230V. In battery mode, the specified voltage regulation is ±5%, with an output frequency of 50/60Hz.
Pure sine wave output is useful for compatible household electronics and electrical equipment. However, appliance compatibility still depends on each device's power requirements and the inverter's operating limits.
7000VA Surge Power
The inverter has a specified surge power of 7000VA for 5 seconds. This temporary surge capability can help accommodate certain loads that require higher power during startup.
Surge capacity does not mean that the inverter can continuously operate a 7000W load. Continuous power must remain within the rated output, and the startup requirements of motors and compressors must be assessed before installation.
93% Peak Efficiency
With a stated peak efficiency of 93%, the Growatt SPF 3500 ES converts battery or DC-side energy into AC power under specified operating conditions. Actual efficiency varies according to load level, input voltage, temperature, and other operating factors.
Correct inverter sizing, appropriate battery selection, and professional installation can help improve the overall performance of a solar power system.
Suitable Applications in Bangladesh
The Growatt SPF 3500 ES can be considered for compatible off-grid solar installations in Bangladesh, including:
Homes requiring backup power for selected appliances
Small offices and commercial spaces
Remote locations where grid electricity is unavailable or unreliable
Solar systems using a compatible 48V battery bank
Backup installations designed around a maximum rated output of 3500W
For the best results, have a qualified solar installer assess the load, battery capacity, solar panel configuration, protective devices, and cable sizing. Verify the inverter's PV input limits, charging specifications, and warranty terms before installation.
Why Consider the Growatt SPF 3500 ES?
The Growatt SPF 3500 ES combines a 3500W rated output, 48V battery architecture, pure sine wave output, and a specified short-duration surge rating. These specifications make it worth considering for appropriately designed off-grid solar and backup power systems.
