Frequently Asked Questions

Q1: Can I replace the 20A fuse with a 25A or 30A fuse?

A1: No, the 25A and 30A fuses are physically larger and do not fit in the fuse holder

Q2: How many fuses come with the inverter?

A2: The inverter comes with x40 fuses (two per PV string input)

Q3: Is it possible to source the fuses here in the US?

A3: Unfortunately, no US distributors stock these fuses so they must be acquired directly from Ginlong Solis through the service portal
