Integrated mppt charge controller

The mppt charge controller integrated in the spf 3500 es optimizes the generation of solar energy by continuously adjusting the voltage and current. This maximizes the efficiency and service life of the Solaranlage by always finding the optimum power point of the solar modules. Adapted in real time to changing light conditions, this charge controller ensures reliable and efficient energy generation that adapts perfectly to your individual needs.

Equalizing charging function

The equalization charging function in the spf 3500 es optimizes battery life by keeping the cells evenly charged. This prevents overcharging and discharging, which makes the battery usable for longer. This minimizes capacity loss and ensures sustained stable performance over time. Intelligent and automatic, this function ensures that your battery bank is always in top condition, increasing the overall performance of the system and making your off-grid energy solution reliable.

Configurable grid or solar input priority

The configurable grid or solar input priority in the spf 3500 es enables individual energy optimization. You decide whether solar energy or the power grid is used as a priority. This adjustment ensures a reliable energy supply - perfect in areas with an unstable power supply or for renewable energy priorities. This function increases independence from the power grid and ensures flexible energy management according to your preferences, while ensuring a constant supply.

Customized modes

The spf 3500 es offers versatile customization options through various user-defined modes. These have been developed for different energy requirements so that you can achieve the optimum use of energy.

Whether you want to maximize the battery charge in low sunlight or aim for peak load optimization, the spf 3500 es allows you to customize the modes to your liking. These functions adapt to different usage profiles and ensure your energy control.

The many customizable modes make the spf 3500 es a flexible solution that fits seamlessly into your lifestyle and energy needs. Whether self-sufficiency, emergency power source or intelligent energy management - the user-defined modes of the spf 3500 es increase energy efficiency and optimize system performance according to your preferences.

Time-controlled charging and power control

The spf 3500 es offers time-controlled charging and precise power control, making your energy management even more efficient.

With the time-controlled charging function, you can specify the preferred times for the inverter to charge the batteries. This allows you to make optimum use of the solar energy during the hours with the highest solar radiation and thus increase the battery capacity for later consumption.

The spf 3500's power control allows you to precisely monitor and adjust energy production and use. You can fine-tune the output power of the inverter as required and thus ensure that your energy supply meets the current requirements. This function is particularly useful for managing unexpected power peaks or controlling the start-up of energy-intensive devices, while ensuring the stability and reliability of your power supply system.
