PEAK SHAVING
Cut demand charges without cutting production
The EMS monitors your grid connection in real time. When consumption approaches the peak threshold, the battery discharges to cover the spike.
solutions
Reduced Energy Cost
Energy isn’t a cost line. It’s a margin lever.
Industrial battery storage that turns volatile energy bills into predictable operating margin and when the timing’s right, a new revenue stream.
HOW IT WORKS
How BESS + EMS turn energy into margin
A Battery Energy Storage System is the hardware. An Energy Management System is the intelligence that decides every second whether it’s more profitable to charge, discharge, store, or sell.
PV SELF-CONSUMPTION
Use what you generate, sell what you don’t need
The EMS stores PV surplus and releases it when your site needs it closing the spread between generation cost and re-import price.
DYNAMIC TARIFF
Charge cheap, discharge when expensive
Forecasting algorithms charge when prices are lowest and discharge during peak tariff hours. No one on your team watches spot prices.
GRID SERVICES
A new revenue line from the same asset
Spare battery capacity can be traded on flexibility markets via Levl Energy, or sold as balancing services where regulation permits.
GRID-LIMIT RELIEF
Add load without rebuilding your connection
Add EV charging or new production without waiting years for a grid upgrade. The battery absorbs peaks; the grid sees a flat profile.
Stack them
A single site rarely uses only one lever. The EMS combines them into a single, optimised margin outcome.
How a German Industrial Site reduce Energy Cost by 52%

Industrial Site
CHALLENGE
Low Self-Consumption of Renewable Energy
The site operates substantial PV system, but energy production and consumption profiles are misaligned. Most electricity demand occurs during early nighttime hours, while solar generation peaks during the day. As a result, a significant share of the available solar energy cannot be utilized onsite, reducing self-consumption and limiting the financial return on the PV investment. In addition, power peaks from the site’s AC charging infrastructure must be managed .
SOLUTION
115 kWh BESS + integrated
The 115 kWh battery energy storage system maximizes on-site utilization of solar energy by storing excess PV generation during the day and supplying power when demand occurs in the early evening. The integrated EMS is configured for PV optimization and Load Management, reducing demand peaks from the site’s AC charging infrastructure while increasing self-consumption of renewable energy.
RESULTS
Reduced Energy cost through Maximum SelfConsumption and Energy Independence
Up to 100% of locally generated solar energy is consumed on-site. During business days, the facility operates with near-complete energy autonomy, significantly reducing reliance on the grid.

PRODUCTS
Two systems. One integrated stack.
You don’t choose between hardware and intelligence. You get both, from a single supplier that owns the full stack.
The questions your CFO is going to ask
Answered directly. If we haven’t covered what you need, a 30-minute call with an engineer will.
What's a realistic payback period for an industrial BESS?
For a mid-sized C&I site in Germany or Central Europe payback typically falls in the 4–7 year range depending on tariff structure, peak-demand profile, and whether PV is already installed. Sites stacking peak shaving, PV self-consumption and dynamic tariff arbitrage tend to land at the lower end. We’ll give you a specific, defensible number for your facility on the first call – not a generic range.
How do you prove the ROI before we commit?
We model it on your actual data. Send us (under NDA if needed) 12 months of interval meter readings, your supply contract, and PV export data if relevant. We return a site-specific business case: capex, operating savings per revenue stream, payback, IRR, and tariff sensitivity. No contract – the model is yours to take to your CFO.
Is Monbat Energy reliable? What certifications does the BESS carry?
Monbat Energy is part of Monbat Group – established 1959, publicly listed, European production. The BESS is certified to UN 38.3, IEC 62619, UL 1973, UL 9540A, IEC 62477-1 LVD, IEC 61000-6-2/4 EMC, EN 50549, VDE-AR-N 4105:2018, and VDE-AR-N 4110:2018. Financing partners and insurers recognise these certifications without additional due diligence.
What warranty do you offer?
An up to 8-year product warranty on the BESS, with performance guarantees on capacity retention over the warranty period. Extended warranty and long-term service agreements are available for bankable projects.
Will installation disrupt our operations?
No. Systems are delivered pre-assembled and pre-tested. Installation for a typical C&I site takes 1–3 weeks; the disruptive window – grid tie-in is usually a single shift, scheduled outside production hours. We coordinate with your facility manager and local DSO from day one.
Is the system compatible with our existing grid connection and PV?
Yes, in almost all cases. The PCS supports 315-450 Vac three-phase, 50/60 Hz, and complies with VDE-AR-N 4105 and 4110 for low- and medium-voltage connections. The EMS integrates with a wide range of PV inverters out of the box and speaks Modbus-RTU/Modbus-TCP to whatever SCADA or BMS you run.
What happens after commissioning – who owns the relationship?
A named regional contact from day one and for the life of the system. Continuous monitoring via the EMS cloud means we often see issues before you do. Germany and Austria are supported from the German office; Central and Eastern Europe from Sofia. No ticket queues, no offshore call centre.
Thirty minutes. An engineer. A defensible number.
