Frequently Asked Questions - SPI 750-4000TL2-HV Growatt
What is the maximum input voltage for the Growatt SPI 750-4000TL2-HV?
The maximum input voltage is 900 V DC. Ensure that the PV array open-circuit voltage does not exceed this limit.
How do I connect the inverter to my home network?
The inverter supports optional Wi-Fi communication via a separate module. Alternatively, use the RS485 or USB port for wired connection.
What type of solar panels are compatible?
Any standard polycrystalline or monocrystalline panels with an MPPT voltage range of 250 V to 800 V DC can be used. Ensure total power does not exceed 4000 W.
Can I install the inverter outdoors?
Yes, the enclosure is rated IP65, meaning it is dust-tight and protected against low-pressure water jets. However, avoid direct sunlight and heavy rain.
How do I reset the inverter after a fault?
Turn off the AC disconnect switch and the DC disconnect switch, wait 5 minutes, then turn them back on. The inverter will restart automatically.
What is the efficiency of this inverter at low load?
The European efficiency is 96.8%, but peak efficiency reaches 97.5%. At low loads (10-20%), efficiency is typically above 95%.
How do I clean the inverter?
Use a dry or slightly damp cloth to wipe the enclosure. Do not use any solvents or abrasive cleaners. Ensure the inverter is off before cleaning.
Does the inverter have a display?
Yes, it features an LCD display showing real-time power, energy yield, status, and fault codes.
What is the warranty period?
Standard warranty is 5 years. It can be extended up to 10 or 15 years with an optional service contract.
Can this inverter operate without a grid connection?
No, it is a grid-tied inverter and requires a stable grid connection to operate. It will shut down if the grid is not present.
