Before, during and after the sale

One partner from proposal to payback

GridVolt is the software that gets the most out of the hardware you already install.

Before the sale

A free simulator that does the modelling for you

Send us the site's half-hourly data and we return a model against the real tariff — self-consumption, peak shaving, tariff optimisation and wholesale trading revenue, all in one payback figure.

  • ✓Site-specific, not blended-rate
  • ✓Assumptions a finance team can interrogate
  • ✓Compare battery and PV sizes side by side

On site

No hardware changes

GridVolt controls the inverter and battery you already sell through the manufacturer's supported interfaces. A small edge controller and a whole-site meter connection is all it adds to your bill of materials.

  • ✓Huawei, Solis, Sigenergy, GoodWe, Schneider and more
  • ✓Remote commissioning support
  • ✓Stays inside manufacturer warranty limits

After install

Revenue your competitors can't quote

GridTrade trades the battery on flexibility and wholesale markets 24/7 and Energy Manager coordinates it with solar and building loads, replanning every 15 minutes. The client keeps their supplier and sees the results in the app.

  • ✓Paybacks compressed from 6–7 years to 3–4
  • ✓Referenceable sites with live results
  • ✓You stay the client's installer

Ways to work with us

Our technology. Your choice of branding.

Offer white-label battery optimisation or use the GridVolt name. Either way, you keep the customer relationship while we manage the battery.

Partner with GridVolt

Add GridVolt’s battery optimisation to your installations without setting up your own branded service. Your customers use our portal and app, while you keep the customer relationship.

White-label partner

Offer battery optimisation as part of your own service, with your name on the portal and app. We provide the software and manage the batteries behind the scenes.

How it works

From site data to a signed project

  1. 1

    Share the site data

    Send us twelve months of half-hourly data, the current tariff and the system size you are proposing.

  2. 2

    Get a site-specific ROI model

    We model tariff optimisation, peak shaving and trading revenue against the real tariff and return numbers a finance team can interrogate.

  3. 3

    Win the project

    Drop the model into your proposal. We are happy to join client calls to walk through the assumptions.

  4. 4

    Commission and earn

    You install as normal. We integrate with the inverter, optimise from day one and keep the client seeing results in the app.

FAQ

Frequently Asked Questions

Which inverters and batteries does GridVolt work with?
GridVolt is hardware-agnostic. We already control Huawei, Solis, Sigenergy, GoodWe, Schneider Electric and ABB systems, and add new brands regularly. If you are specifying something else, send us the model and we will confirm compatibility before you quote.
What do you need from me to build an ROI model?
Twelve months of half-hourly import (and export, if any) data, the site’s current tariff, and the battery and PV sizes you are proposing. We return a site-specific model showing savings and trading revenue against the real tariff, usually within a few working days.
Does the client have to change energy supplier?
No. GridVolt sits alongside the existing supply contract. Tariff optimisation works against whatever tariff the client is on, and GridTrade revenue is settled separately by GridVolt as the trading party.
Who commissions and supports the system after install?
You install the battery, inverter and metering as normal. GridVolt supplies the edge controller and supports commissioning remotely, then monitors and optimises the site 24/7. You remain the client’s installer and first point of contact for hardware.
Does GridVolt affect the manufacturer warranty?
GridVolt controls the battery through the manufacturer’s supported interfaces and respects the operating limits set by the BMS and inverter. We do not bypass warranty-relevant limits, and we can hold back a minimum reserve if the client wants one.

Installer knowledge base

Straight answers to the questions clients ask

Browse the knowledge base →

Who is responsible if the battery controller misses a trade?

It depends on what caused the missed trade and what the contracts say. GridVolt can investigate using trading, controller, battery, communications and meter records where available. Before handover, make sure the client knows who supports each part of the system and who to contact if a trade is missed.

Can a third-party EMS stay within the battery manufacturer's warranty limits?

Yes, if the battery maker allows outside control and the EMS stays inside the warranty rules. Check limits for charge and discharge power, state of charge, temperature, cycling and total energy used over the battery’s life. Being inside the battery’s safety limits does not automatically mean you are inside its warranty.

How large does a commercial battery need to be before trading is worthwhile in Great Britain?

There is no fixed GB minimum battery size for trading under P415. Some providers use 100 kWh as a first filter, but what matters more is how much spare battery power, usable energy and import or export headroom the site has after its own needs are covered. Smaller batteries can still be worth checking.

What happens to battery control if the site loses its internet connection?

The battery should keep a safe local plan if the internet goes down. If the on-site controller can still talk to the meter and inverter, it may keep following its saved schedule. If that local link also fails, the inverter should move to an agreed fallback setting after a set timeout.

When is it worth adding a separate EMS to a commercial battery?

Add a separate EMS when it can save or earn more money than it costs to run. Compare the same battery using the inverter’s best controls and the separate EMS, using the same site data, tariff and battery settings. The extra saving after controller, software, support and other EMS costs is the figure that matters.

Does battery trading still pay if the customer is already on a wholesale-linked tariff like Agile?

Yes, battery trading can still add income on a wholesale-linked tariff, but the two uses can overlap. The battery may already be charging in cheap periods and discharging in expensive ones to cut the bill. Ask GridVolt to check whether GridTrade adds extra value before putting any trading figure in the proposal.
