What Altenergy Power System does
Altenergy Power System (APsystems) is a Shanghai Stock Exchange-listed (SH.688348) provider of module-level power electronics (MLPE) for the global solar PV industry, founded in Silicon Valley in 2010 and now operating through 6 global business units serving 160+ countries. The company designs and manufactures multi-module microinverters (DS3 series at 640VA/748VA/880VA outputs, QT2 three-phase for commercial, and the EZ1 plug-in DIY unit), residential energy storage systems (APstorage ELS 11.4K and APbattery 10kW), rapid shutdown devices (APsmart RSD), and supporting infrastructure including ECU-C/R gateways, LTE dongles, Combiner Boxes, and the APmeter zero-export solution. Core technology differentiation centers on the multi-module architecture with 20% fewer components than single-module alternatives, 97% peak efficiency, encrypted Zigbee wireless communication, and module-level MPPT, all managed through the AP EasyPower mobile application.
APsystems operates a hybrid go-to-market model combining direct-to-consumer e-commerce (APshop, Shopify storefront) with a tiered certified distributor and installer network anchored by national partners Greentech Renewables and Soligent, plus regional EZ1 distributors (NAZ Solar Electric, Green Box Solar). The company targets residential homeowners, DIY/portable solar users, professional solar installers, and commercial & industrial customers through dedicated Homeowner and Installer tracks on its US website, supported by the APsystems Academy training portal and Triple-E partner program. Pricing is unit-based (DS3-880 at $295, DS3-S at $225, EZ1 at $325, APmeter at $90, ECU-R at $315), with US operations headquartered in Austin, TX under US Country Director Doug Hewitt and a regional BDM team covering Mountain West, Texas/Southeast, Northeast, and National C&I.
