Ginlong (Solis) Technologies unveiled three series of new energy storage inverters at its Solis Inno Day and New Product Launch 2022, held virtually on 10 November 20221. The company describes itself as one of the most experienced and largest inverter producers in the world, established in 2005 and listed under stock code 300763.SZ1.
Two of the three series are sixth-generation energy storage inverters for the European market1. Xinyu Guan, Solis Energy Storage Product Manager, said the European models include a charge and discharge current of 125A for a global equivalent power range, and a "1+N" full energy storage scenario application, which the company says allows integration of modules and functionalities for smart matching between user demand and scenarios1. Installation time is reduced by 20%, according to the same statement1.
A third series, described as technically upgraded energy storage inverters, was introduced for the North American market, designed around that market's specific needs1. The company says it optimises its inverters for each regional market1. Solis also presented Solis Sunny, a new brand image, for the first time at the event1.
"Solis has launched two new 6th-generation energy storage inverters for Europe this time. These inverters have many functions, including a large charge and discharge current of 125A for a global equivalent power range; and a '1+N' full energy storage scenario application."
The announcement gives no pricing, no efficiency figures, no warranty terms and no UK availability date for any of the three series1. Solis inverters already appear in the UK market, and the company's storage inverter range is covered in the site's guide to Solis storage inverters and home batteries and its Solis solar inverters page.
Why it matters for households
An energy storage inverter is the core device in a home battery system: it converts direct current from a battery into usable household alternating current and manages charging and discharging1. Solis states that the inverter supports correction of grid instabilities and improves power regulation and safety assurance1.
For a household considering a battery, the practical questions are whether a given inverter is compatible with the battery being installed, whether it can be added to later, and how long installation takes. The 125A charge and discharge current and the "1+N" scenario concept are the company's claims about flexibility and matching to household demand, and the 20% reduction in installation time is its claim about fitting work1. None of these claims is quantified in the announcement beyond the figures given, and no independent test data is cited1.
A home's energy independence depends on how much of its own solar generation it can store and use rather than export or buy back. Higher charge and discharge current can allow faster movement of power into and out of a battery, which matters where a household wants to charge a battery quickly from solar or discharge it to cover a peak. The announcement does not state usable capacity, round-trip efficiency or backup capability for any of the new series, so the effect on a specific home cannot be judged from it1. Hybrid units that combine solar conversion and battery management in one device are covered in the site's guide to hybrid solar inverters, and the wider market in the home batteries and solar PV sections.
What happens next
No launch dates, UK certification, availability or pricing for the new series have been reported1. Solis has published a recording of the event, which it says can be found by searching for "Solis Innovation Day" on YouTube1.
