Solar-storage-charging integrated systems answer a problem that grid connections alone increasingly cannot: adding high-power EV charging to a site whose electrical service was never sized for it. By combining on-site **photovoltaic generation**, **battery energy storage** and charging hardware behind a single energy-management system, Entogo lets operators charge vehicles from solar and off-peak energy, cap demand charges, and keep charging available when the local grid is constrained or an interconnection upgrade is still pending. The system is delivered as a coordinated package rather than separately procured parts. Photovoltaic arrays, the battery storage buffer, the power conversion stage and **AC or DC charging** are matched to the site’s load profile and capacity, then validated as one system before shipment — the same engineering-to-delivery discipline Entogo applies across more than 1,200 delivered projects. ## How the system works together The energy-management layer prioritizes **solar self-consumption**: photovoltaic output charges vehicles and the battery first, with the grid filling only the gap. During expensive demand windows the battery discharges to shave peaks and shift load to off-peak hours, and in grid-interactive modes the system can support broader load-management goals where local rules permit. When the grid is interrupted, stored energy keeps charging and critical loads running. Because charging draws on the battery rather than the service entrance, sites can offer **DC fast charging** at power levels their utility connection alone could not sustain — often avoiding or deferring a service upgrade entirely. ## Who it's for - Real estate & property developers - Public buildings & municipalities - Retail and commercial sites - Fleet & depot operators - Charging network operators ## Applicable codes & standards North American codes and standards that govern this class of installation. | Code / standard | Scope | | --- | --- | | UL 9540 | Energy storage system & equipment safety | | UL 1741 SA/SB | Inverters & grid-interconnection equipment | | IEEE 1547 | Distributed energy resource interconnection | | UL 2202 / 2594 | EV charging system equipment | | NEC Art. 625 / 706 | EV charging & energy storage installation | | OCPP | Open charge-point management protocol | Payment & financing Flexible payment terms and project financing are available for qualified projects — milestone-based plans, reduced up-front payments and third-party financing.

A battery buffer lets operators add fast charging without a costly utility upgrade, while reducing demand charges and keeping chargers available when the grid is constrained. - **Can the system operate during a grid outage?**: Yes. Battery storage supports resilient and off-grid modes, keeping charging and critical loads available where grid power is interrupted, limited, or where an interconnection is still pending. - **Which sites are a good fit?**: Retail and commercial properties, real-estate developments, public buildings, and fleet or depot sites that want fast charging, lower energy costs and resilience without waiting on a major service upgrade.
