Hybrid Energy Storage Solutions (Battery + Grid Integration)

True energy independence takes more than a battery — it takes a system that blends solar, storage, and the grid intelligently. This collection is where Portlandia Electric Supply's hybrid energy storage solutions live: complete, engineered packages that combine hybrid inverters, LiFePO4 battery banks, smart load management, and grid integration in one matched design.

Two flagship approaches anchor the collection. The EG4 GridBOSS MID V2 is a 200A service-entrance microgrid interconnect device — the intelligent gateway that lets a FlexBOSS hybrid inverter, batteries, generator, and grid all share one service without a stack of transfer switches. The Fortress Power Avalon HV Pro ESS is the all-in-one alternative: a 7.6kW inverter, 29.4kWh of high-voltage battery storage, a smart energy panel, and a 200A automatic transfer switch in a single integrated enclosure, sized to back up most whole homes out of the box.

The right choice depends on your service size, existing solar, and how much of the home you want backed up. GridBOSS suits custom builds and expansions; Avalon suits buyers who want one SKU, one warranty, one install. Either way, our team designs these systems daily — send us your panel schedule, solar array size, and critical loads list, and we will spec the complete battery-plus-grid package with wiring guidance before you buy.
