For Scalable, Flexible Energy Storage Systems

For residential energy storage pros, installation speed and site flexibility are the ultimate competitive edges. Briggs & Stratton Energy Solutions is redefining the standard for high-performance battery stacks with the introduction of dual-wire routing for the SimpliPHI® 6.6 Battery.

The high-performance Briggs & Stratton 6.6 Battery Controller for the SimpliPHI 6.6 stackable battery, equipped with new double-sided connectors, gives you full flexibility–allowing inverter connections to be routed from either the left or right side of the stack. This streamlined design simplifies installation while maintaining secure, high-reliability communication with your system.

Dual-Wire Routing: The Freedom to Choose Your Path

Dual-wire routing solves your toughest site constraints:

Eliminate Cable "Cross-Over": Route your 4/0 AWG cables directly toward the inverter, regardless of which side it’s mounted on.
Cleaner Management: Shorter cable runs mean less voltage drop, lower material costs, and a significantly more professional aesthetic for the homeowner.
Flexible Integration: Achieve native closed-loop communication with leading 48V inverter platforms—including Sol-Ark®, Growatt®, Megarevo®, and EG4®. The included cross-over dongle supports direct integration where required, while deployments with EnergyTrak 2.0 eliminate the need for additional hardware by enabling streamlined system-level communication.

Why the SimpliPHI 6.6 is an Installer’s Powerhouse

The SimpliPHI 6.6 was already built for speed, but this update makes it one of the most adaptable systems on the market.

Industry-Leading Speed: You can assemble a full stack of three batteries in under five minutes.
The RapidStak™ Advantage: Our self-guiding, wire-free connectors integrate power and communications into a single "click" connection—no DIP switches, no complex pin-outs, and zero wiring between modules in a stack.
Extreme Scalability: Start small with 6.65 kWh or scale up to 119.7 kWh by connecting 6 stacks (up to 18 batteries total) in parallel.
Unmatched Durability: The system is IP65-rated for all-weather indoor or outdoor versatility and features a cobalt-free LFP chemistry.
