Solis S6-EH1P(3.8-11.4)K-H-US

The Solis S6-EH1P(3.8-11.4)K-H-US is a family of single-phase hybrid inverters from Solis. They are transformerless, bi-directional, utility-interactive units with grid support, and they are permanently connected. The certification listing names the 3.8, 5, 7.6, 9.9, 10 and 11.4 kW models, among others. Every model has an integrated AFCI for DC arc-fault protection and has ground fault detection. DC reverse-polarity protection covers the PV inputs only. The technical data refers to a separate compatibility list for the supported rapid shutdown receivers and for the number of batteries per inverter. The family holds a CSA certification under a product class covering power systems equipment certified to U.S. standards. The alarm messages include 12Power-FAULT for a 12 V supply fault, AFCI Check FAULT for an AFCI self-check fault, and DSP-B-FAULT for lost communication between the main and slave DSPs. For each one, the advice is to restart the inverter or contact the installer.

<!-- review notes

• sentence 1: support check: partial - The passages support transformerless, bi-directional, grid support, utility-interactive and permanently connected, but 'single-phase hybrid inverters' is not stated (only the 'EH1P' model name hints at it), and 'solis' alone doesn't establish the maker.
• sentence 3: support check: partial - Evidence covers only the 3.8, 5, 7.6, 9.9, 10 and 11.4 kW models, so 'every model' is overstated, as the 6 and 8 kW models are not covered.
• sentence 1: review: partial - The CSA listing supports bi-directional, transformerless, grid support, utility interactive and permanently connected, but 'single-phase hybrid' is not stated in the passages. -->
