Also known as: Solis-1P3.6K-4G-US, Solis-1P5K-4G-US, Solis-1P6K-4G-US, Solis-1P7.6K-4G-US, Solis-1P10K-4G-US, 4G Series Grid Inverter
Category: Inverters
Make: solis
Product level: family

The Solis-1P 4G-US is a family of single-phase grid-tied inverters made by Solis, with models from 3.6K to 10K. The 6K, 7.6K and 10K models are rated at 6 kW, 7.6 kW and 10 kW of output, accept up to 600 V DC input and run on a 60 Hz grid. CEC efficiency is 96.6% on the 3.6K, 97.1% on the 5K and 97.5% on the 6K through 10K models. The 7.6K and 10K models use a transformerless topology and have an LCD display. RS-485 is the standard communication interface, and cellular or Wi-Fi are available as options. The inverter has DC arc-fault protection. An AFCI Check FAULT alarm means the AFCI module failed its self-check. To clear it, reset the inverter by switching the DC off and back on, and replace the inverter if the fault returns.

<!-- review notes

sentence 1: support check: partial - Models 3.6K–10K and Solis name shown, but single-phase and grid-tied are only loosely implied (1P, grid inverter).
sentence 4: support check: partial - Transformerless stated for both, but LCD display only given for the 10K, not 7.6K.
sentence 6: support check: partial - AFCI self-check fault and reset/replace steps are stated, but DC arc-fault protection is only implied by the section title and 'if the fault returns' is an interpretation.
sentence 1: review: partial - The passages name the 3.6K to 10K models as '4G Series Grid Inverter', but single-phase is only implied by the '1P' in the model names.
sentence 4: review: partial - The passages say both the 7.6K and 10K are transformerless, but they list an LCD display only for the 10K, not the 7.6K. -->
