GridVest Configured Storage Solutions
Pre-selected BESS system configurations — combining Tier-1 batteries, inverters, and EMS into tested, deployment-ready packages.
Battery storage, delivered differently
We bring together sourcing, financing, and deployment under one contract — helping teams reduce friction and move from concept to operation faster.
Battery storage system packages – vetted by the GridVest team
Each system – consisting of a recommended battery, inverter and EMS combination – has been validated by GridVest's technical team based on real-world project experience and direct supplier relationships.
These configurations represent only a sample of starting points – field-tested by GridVest's engineering team. Every project is different, and GridVest works with an even broader range of equipment and custom configurations beyond what's listed here.
Complete BESS packages up to 4MWh
These cabinet-based configured solutions are purpose-built for commercial and industrial applications — from demand charge management and backup power to behind-the-meter solar optimization.
See below for a list of pre-validated system combinations to reduce procurement guesswork and enable faster delivery timelines.
CATL EnerOne+
The CATL EnerOne+ anchors the top of the lineup. Built around battery technology and liquid-cooled from the world's largest cell manufacturer and scalable from 372 kWh to 3 MWh. Uniquely in this portfolio, it offers a choice of power conversion partner: Dynapower or EPC Power, letting the inverter selection follow the project's voltage class, coupling architecture, and site requirements rather than forcing a one-size-fits-all pairing. With Battalion Energy and Elexity EMS integration driving dispatch, the EnerOne+ is aimed squarely at ROI: demand charge reduction, energy arbitrage, and program revenue at industrial and utility-adjacent scale.

FEOC COMPLIANT
Generac SBE
The Generac SBE is a fully integrated, FEOC-compliant storage system from a name synonymous with backup power. With the inverter built in and energy management handled by Ageto — Generac's own controls platform — the SBE delivers a true single-vendor solution: one manufacturer standing behind the entire stack, from cells to dispatch software. Scalable from 258 kWh to 1.7 MWh, it fits mid-size to large C&I projects pursuing both ROI and resiliency, with demand charge management and rate optimization layered on top of the dependable backup capability Generac is known for. The system carries a full certification stack.

Pytes HV48100 SE
The Pytes HV48100 SE pairs Pytes' high-voltage rack-mounted battery platform with a Sol-Ark inverter for a flexible, cost-effective storage solution in the commercial and light C&I space. The modular rack design makes capacity easy to right-size — scale from 60 kWh to 600 kWh by adding modules rather than committing to a fixed cabinet — which keeps upfront costs aligned with actual load requirements. Compatible with Energy Toolbase, Ampra Grid, and EnergyBoom EMS platforms, the system supports demand charge management, time-of-use arbitrage, and backup power for projects targeting both ROI and resiliency.

Discover Energy Systems 208V
The Discover Energy Systems package pairs Discover's integrated LFP battery cabinet with a Sol-Ark inverter, stepping up in scale for larger commercial and industrial loads. With capacity from 210 kWh to 1 MWh, it's built for facilities where demand charges and outage exposure are significant enough to justify utility-grade storage — think manufacturing, cold storage, and multi-building campuses. Compatible with Energy Toolbase and Ampra Grid EMS platforms, the system supports demand charge management, time-of-use arbitrage, and backup power in a single deployment.

CPS 261
The CPS 261 is an all-in-one storage solution from Chint Power Systems, combining battery and inverter from a single manufacturer for a tightly integrated, economics-first deployment. Scalable from 261 kWh to 1.5 MWh, it's purpose-built for C&I projects where the business case rests on returns — demand charge reduction, time-of-use arbitrage, and participation in utility programs — rather than backup power. Elexity's EMS handles dispatch optimization, automating charge and discharge decisions to maximize savings against the facility's rate structure.
