Advantages over Classic Battery Storage Systems

1. Specifically Developed for Hybrid Operation

Unlike many standard battery storage systems, the EHR 45/90 is designed as a Battery Power Generator. It handles:

• Peak Shaving – covering peak loads

• Load Sharing – intelligent load distribution

• Low Load Management – avoiding inefficient generator partial load

• UPS Function – uninterruptible power supply

Especially on construction sites with highly fluctuating load profiles, this ensures optimal efficiency.

2. Reduction of Diesel Consumption and Emissions

In combination with a HIMOINSA Rental power generator, the generator only runs when actually needed. The storage system handles:

• Night operation without engine running

• Low load phases

• Peak loads

This reduces:

• Fuel consumption

• Maintenance costs

• CO₂ emissions

• Noise pollution

This is a crucial advantage, especially on inner-city construction sites or in noise-sensitive areas.

3. Robust LiFePO4 Technology for Demanding Applications

The integrated LFP batteries offer:

• High safety

• 90% usable capacity

• Up to 6,000 charging cycles

• Overcurrent capability up to 2 times the nominal current

Compared to NMC systems, LiFePO4 is more thermally stable and better suited for continuous construction site loads.

4. Intelligent Control with HICORE System

The integrated HICORE control module with 4.3” TFT display enables easy operation and optimal energy management.

Functions:

• Plug & Play mode

• Automatic operation optimization

• Remote generator start

• 3G/4G remote monitoring

• Web app and C2Cloud connection

This allows for analysis of load profiles and targeted optimization of energy costs.

5. Photovoltaic Integration Possible

The EHR 45/90 features:

• 2 × 4 kW MPPT

• PV short-circuit current up to 140 A

• MC4 connectors

Thus, it can be integrated into temporary solar construction power solutions – ideal for sustainable construction projects.

Why the EHR 45/90 is Ideal for Construction Sites

Construction sites are characterized by fluctuating loads, short peaks, and long low-load phases. A pure diesel generator often runs inefficiently in such conditions.

The EHR 45/90:

• buffers peak loads

• stabilizes the power supply

• prevents generator oversizing

• reduces engine running times

• enables silent night operation

In combination with a HIMOINSA Rental genset, it creates an economical, flexible, and future-proof hybrid solution.

Typical Applications

• Construction sites (building and civil engineering)

• Infrastructure projects

• Events

• Industrial facilities

• Emergency power and temporary solutions

• Hybrid solutions with diesel generators
