APsystems offers cost-effective microinverter solutions with dual and quad module designs that simplify installation while delivering panel-level optimization.
APsystems (Altenergy Power System Inc.) is a global leader in multi-platform Module-Level Power Electronics (MLPE). Their key innovation is dual- and quad-module microinverters — one unit serves multiple panels instead of one-per-panel, which lowers system cost and speeds installation while still delivering panel-level monitoring and optimization. A strong value play when budget matters and the roof has minimal shading complexity.
Key Features
Dual-module DS3 design splits the cost of a microinverter across two panels. Quad-module options take that further. Lower hardware cost than one-per-panel competitors without sacrificing panel-level optimization.
Fewer microinverter units on the roof means faster install, less rooftop wiring, and fewer connection points to maintain over the life of the system.
Each panel still operates independently — partial shading on one panel does not drag down the others.
The Energy Monitoring & Analysis (EMA) app provides per-panel production data, fault detection, and lifetime reporting.
DS3 dual-module microinverters for most residential builds. QS1 quad-module for tight power budgets where every dollar matters.
Industry-standard warranty coverage with responsive North American support.
