Stromherz cares about the environment, LifePO4 batteries are safe and provide independent, reliable storage of solar energy. Our motto «Never Stop Charging» means the energy supplied day and night. Lightning with a curved beginning and end in the logo of the letter «S» denote the cycle of our system, receiving energy from the Sun and transforming it into the usual energy for our use, and storage in Stromherz systems.

Our products and our team are working 24 hours a day to create the best experience and products for users. Stromherz devices are reliable and easy to use. We work hard to ensure that our product exceeds international standards.

The device is available in the following power classes from 6 kW to 12 kW and has a DC input voltage range of 620 V.

The inverter measures 550 x 410 x 175 mm and weighs between 26 and 28 kg. It offers efficiency from 98.1% to 98.2% and European efficiency of 97.3% for the smallest device and 97.4% for the largest. The product is equipped with two maximum power point tracking (MPPT) inputs, and the MPPT range is 150-850 V.

The maximum input current (DC) is 13 A and the maximum short circuit current is 18 A. It is equipped with IP65 protection, natural convection cooling and can be used in projects at altitudes up to 4000 meters and at temperatures ranging from -30 to 60 degrees Celsius. The inverter uses a lithium-ion battery with a voltage range of 76.8 V and a maximum charge / discharge current of 25 A.

The backup port of the inverter can be connected to inductive loads such as air conditioners, hair dryers or water pumps. The device can provide an uninterruptible power supply (UPS) in the event of a power outage. In the event of a mains failure, the inverter will automatically switch to standby mode within 10ms, and the main loads connected to the standby side will not be disturbed, the company added. The hybrid inverter offers multiple connections with up to 10 parallel modules to increase the AC output and battery capacity to make it suitable for commercial applications. The power export limiting function in the hybrid inverter is enabled, the inverter will output power according to the load consumed in each phase. “If there is excess power trying to export to the grid, the inverter will charge the battery before reducing the power coming from the PV panel to balance the input and output power.
