Solis

Solis is the inverter brand of Ginlong Technologies, which has its headquarters in Xiangshan County, Ningbo, Zhejiang Province, China. The company also has a US office in Dublin, Ohio, and publishes application notes for its US inverters, for example on how they handle the AC neutral. Its US grid-tied lineup includes transformerless grid support utility interactive PV inverters, such as the S5-GC75K-US to S5-GC100K-US models and the S6-GU EHV models. These are wall mounted and permanently connected. Solis also makes S6-EH hybrid inverters. In generator mode they synchronize with the generator and run grid-following, and some models have an RJ45 DRM port where the region requires it. SolisCloud brings in time-of-use electricity prices from Octopus, Nord Pool and Flatpeak for several European countries and uses them in its energy management.

<!-- review notes

• sentence 1: support check: partial - Passages give the Ginlong address in Xiangshan County, Ningbo, Zhejiang, but do not explicitly say Solis is Ginlong's inverter brand or that this is the headquarters (u9 names a manufacturer 'Ginlong (Ningbo)' and a Solis manual).
• sentence 2: support check: partial - US office in Dublin, OH is stated and an application note on Solis US inverters and the ac Neutral exists, but the passage only gives a title, not what the note says or that it's about handling the neutral beyond the title.
• sentence 4: support check: partial - Generator mode grid-following synchronization and an RJ45 DRM port for some regions are stated, but the passages don't say that the DRM port is on some S6-EH models specifically (u21 not tied to S6-EH).
• sentence 1: review: partial - The passages give the Ginlong Technologies address in Xiangshan County, Ningbo, Zhejiang, but never say Solis is Ginlong's inverter brand or that the address is its headquarters. -->
