Solis announced the launch of the S6 Advanced Power Hybrid Inverter on 10 May 2023. The company describes the unit as its latest product, built around generator connectivity and multiple input methods1.
"has announced the launch of their latest product, the S6 Advanced Power Hybrid Inverter"
The S6 offers automatic UPS switching and up to 10 seconds of 200% surge power backup overload capability, according to the announcement1. It supports both single-phase and three-phase flexible connection, with a maximum of 48kW in parallel, and can handle up to 190A maximum charge and discharge current1. Six customisable charge and discharge time settings are included1.
The inverter is compatible with both lead-acid and lithium batteries and carries multiple battery protection features1. It also supports peak shaving control in both "self-use" and "generator" modes1. Solis states that the S6 is the product of years of innovation and development work1.
Solis Technologies was established in 2005 and describes itself as one of the leading providers of string inverters worldwide1. The company says it has global offices and technical after-sales service centres in multiple locations including the United Kingdom1. It states that it ranked third in global PV inverter shipment, second in global single-phase and third in global three-phase string market share by shipments1. No UK retail pricing, availability date or warranty terms for the S6 were given in the announcement, and these have not been reported1.
Why it matters for households
A hybrid inverter combines solar generation and battery storage in one unit, which is the arrangement most homes need if they want to store their own generation rather than export it all. The features Solis highlights point at two different household situations.
Generator connectivity matters where a home has a backup generator, or where one is being considered, because it allows the inverter to work alongside that generator rather than instead of it. Automatic UPS switching and the surge capability are aimed at keeping circuits running through a grid outage, which is the part of energy independence that a battery alone does not always deliver. The 48kW parallel maximum and 190A charge and discharge current are figures well beyond a typical single home, so they are more relevant to larger properties or installations built up over time.
Compatibility with both lead-acid and lithium batteries widens the range of storage a household could pair with the unit, though the announcement gives no efficiency, cycle life or warranty figures for either chemistry. Peak shaving control in self-use and generator modes relates to limiting how much power is drawn from the grid at peak times, which is a running-cost question rather than a backup one. For anyone weighing a string inverter against a hybrid, the S6 sits on the hybrid side of that choice. Solis is one of several brands covered in the site's manufacturer listings, and its UK range is set out in the Solis inverters guide.
