APsystems to Launch QS1 Four-Module 1200W Microinverter at Solar Power International

The first of its kind, the QS1 from APsystems is designed to accommodate today's high output PV panels, offer enhanced capability and significantly reduce installation time and costs.

APsystems will unveil the QS1, a four-module, single phase microinverter for residential applications at the Solar Power International trade show in Anaheim. A new design for APsystems, the QS1 offers 75% faster installation time, while offering the highest peak output power and up to 3X faster transmission speed than conventional microinverters. A wider MPPT voltage range will result in a greater energy harvest for homeowners.


The first of its kind, the QS1 is designed to accommodate todays high output PV panels, offer enhanced capability and significantly reduce installation time and costs while providing an unprecedented level of power with four independent MPPT per channel. Common AC trunk cabling with the dual-module YC600 offers flexible mix-and-match compatibility on the same circuit and with the same gateway (ECU-R or ECU-C).

The unit also builds on the successful APsystems line of multi-module microinverters, offering reduced logistics costs and integrated communication and connection features.

The new microinverter will debut at the APsystems booth #2838 September 25-27 at SPI.

SolarEdge Technologies - EV Charging Single Phase Inverter

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power SolarEdge's EV charging single phase inverter offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the world's first EV charger with an integrated PV inverter. Reducing the hassle of installing separately a standalone EV charger and a PV inverter, the EV charging inverter eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel. Whether you own an EV now or just want to be EV-ready, future-proof your home with SolarEdge.
