This outdoor setup is designed to withstand various weather conditions. With an IP65 rating, the system is protected against dust and water jets, ensuring durability and reliability even in demanding environments.
Maxus 125Kw/258kWh, an all-in-one commercial and industrial ESS with liquid cooling, is integrated with an energy storage converter, battery, BMS, EMS, thermal management, power distribution and fire protection. The all-in-one design is easy to install and O&M and connects with all other Maxus Products and automatically deals with dynamic electricity prices via various EMS systems. Prismatic cells deliver the highest quality and long lifespan with 8000 cycles.
Liquid cooling:
The temperature deviation of battery cells in the whole system is within ±1.5°C due to
intelligent liquid cooling system. It extends system life by up to 30% and increases system efficiency in the long term
up to 88.5%.
Safe
The system has four management levels with short-circuit protection, over-voltage protection, under-voltage protection, over-temperature protection, etc.
Mandatory safety and European certificates, inverter and batteries:
EN 50549-1 for the inverter of the Maxus and applies to power-generating units connected to low-voltage grids and EN 50549-2 applies to power-generating units connected to medium-voltage grids.

UN38.3
This system is recommended for offices and utility applications with an average annual consumption of 60,000 to 90,000 kWh. With a capacity of 256 kWh and modular expandability, you can store significant amounts of energy. With a minimum connection of 3x80A and a 3-phase configuration, the system is compatible with most existing large electrical installations. Hardware price excludes VAT
Installation
The Gridbuilder’s smart battery solution works both without and in combination with solar panels. If you already have solar panels, the battery will be added as a ‘retrofit installation’. The system is added to an existing solar panel system. This allows you to store the excess energy and use or sell it later. A ‘retrofit installation’ can be applied to all brands of solar panel inverters, so we can read all models and brands.
We determine in advance where it is best to place the battery. Outdoor setups are also possible in a special outdoor cabinet. The final installation will take a full day, depending on the situation.
Control subscription
With this battery solution you immediately save on your energy bill by ‘trading’ electricity on the various energy markets and you contribute to balancing the supply and demand of electricity on the grid. The software ensures that electricity is purchased at the cheapest hours of the day and sold at the most expensive hours, based on a dynamic energy contract. Because netting is currently allowed in the Netherlands, the home battery yields the most in this way.
As soon as netting stops, the algorithm automatically adjusts to first charging with your own solar power – supplemented with charging at the cheapest hours from the grid. This is then used to get your meter towards zero! In addition, surpluses from our own generation and from the grid for the meter (the electricity grid) will be traded. This way you always have the cheapest electricity and the optimal efficiency of the day, even in the winter months.
Even without solar panels you can save a lot on your energy bill and you can be part of a larger network.
Monthly terminable
The Gridbuilder provides the control service via a free ‘entry-level’ subscription. We maintain and develop the algorithm every day, so that the most out of the home battery is obtained. As long as the subscription runs, the battery system is actively controlled and the app can monitor the total amount generated, purchased, used, sold and earned. The Gridbuilder control is connected to the local Wi-Fi network via a hardware box.
Warranty
Due to daily use of the battery, it loses a very small amount of power over the years, so slightly less capacity remains. The minimum capacity that the battery must have after a certain use is stated in the warranty. The batteries have the following warranty, whichever comes first:
- After 10 years, at least 80% of the original capacity remains.
- minimum 6000 charging cycles up to 10000 cycles (depending on brand); during active charging and discharging, an average of 1.5 cycles are run per day. This means a lifespan of 11 years with a warranty of 6000 cycles.
Parameters are incorporated into the control that protect the battery against unnecessarily rapid wear.
