Pre-Wired Multi Stacked AC Coupled Systems

SunWize AC CoupledSunWize has partnered with Magnum, MK-DEKA, & UPG to bring a new line of pre-wired inverter-battery systems that can be AC Coupled to most existing solar installations! Available in mix-and-matching inverter / battery subassemblies, our AC Coupled System options are excellent ways to add energy storage to an existing solar system!

Magnum MS-PAE Inverter Chargers

These systems feature plug-and-play pre-wired inverter power centers available between 4.4kW and 17.6kW. These multi-stacked power systems are based on the reliable & parallel stacking Magnum MS-PAE 120/240V Series Inverter / Charger.

Robust Battery Assembly Options

SunWize AC Coupled Systems feature several battery bank configuration options to meet your exact project requirements. Our battery banks are pre-wired at 48VDC and are available in either Gel or AGM. Our battery assemblies include rack or enclosure, available in several different configurations. Mix and match the right sized battery assembly for your exact needs, ranging between 265Ah (1 String 8D) and 1,664Ah (4 Strings L16) of energy storage at 48VDC!

Single Stack 4.4kW Inverter System Example Layout

Single Stack SystemOur pre-wired systems make installing an AC Couple system easy, since all of our configurations are not only pre-designed to be plug-and-play compatible, but they are also already pre-assembled and wired to make on-site installation as simple as possible. Choose the Size inverter system you need for your application (between 4.4kW and 17.6kW), then choose the size battery system that you want to support your loads (between 265Ah and 1,664 Ah at 48VDC).
