Battery Storage Equipment: When and Where You Need It

  • We source the best stationary storage solutions on the market for commercial & industrial projects, stock them in our warehouse, and provide a manufacturer-backed ten-year warranty.

    Currently, we supply battery systems from CATL, SYL, BYD, & Sol-Ark and we are exploring others.

    We can have systems on-site in as a little as six weeks.

  • We combine our batteries with the optimal power control systems (PCS/Inverters) for each application. We stock PCS/inverters from 45kW-1.5MW for both 208-volt and 480-volt commercial and industrial applications.

    We source from brands such as Delta, Dynapower, EPC Power, Oztek, Power Electronics & more.

  • We source high quality energy management systems (EMS) and microgrid controllers from companies such as Molecule EMS, Up Energy, Ageto, ComAp and more.

    These systems are the brains of the operation and help to optimize your economic savings and can manage critical back up loads and diesel generators islanding and off grid power.

  • We understand that implementing energy storage solutions can be a significant investment. That's why GridVest offers competitive pricing and favorable payment terms, even to entities with limited credit history to make energy storage accessible to businesses of all sizes.

    Typical battery suppliers require 30-50% of the payment upfront upon an initial order. We require as little as 5% down to secure a battery system allows contractors to align their payment with when they get paid.

    Our team works closely with developers, installers, and end users to develop tailored financing plans that fit their budgets and maximize return on investment.
