It has a built-in 80A MPPT charge controller. It is possible to connect an additional Wi-Fi module, available from our offer. It does not support a BMS. Compatible Wi-Fi module can be connected: product code 53962.

How does a hybrid inverter work in off-grid mode?

The efficiency of a photovoltaic system depends on selecting the appropriate inverter, also known as a solar inverter. The inverter plays a key role in this system, converting the direct current (DC) generated by the photovoltaic panels into alternating current (AC) for use by home appliances . An off-grid hybrid inverter connects the photovoltaic system, energy storage, and the power grid .

It uses excess solar energy to power loads and charge the battery. When energy production exceeds current demand, the excess current can be transferred to charge LiFePO4, AGM, or GEL batteries, or to energy storage, allowing energy to be stored for later use, for example, at night or on cloudy days . The hybrid inverter can automatically switch to off-grid mode, supplying power from the batteries .

Increased electricity production with a significant decrease in operating costs

The battery charging inverter uses a modern 80A MPPT charge controller that maximizes the power drawn from the photovoltaic panels using advanced maximum power point tracking technology.

This feature significantly improves the efficiency of the photovoltaic system , allowing it to maintain high power even in low-intensity conditions. Additionally, the controller monitors the battery's operation and charging process, protecting the battery from damage.

Constant monitoring of battery operating parameters

The product features a multifunctional, easy-to-use LCD display with a control panel. It facilitates monitoring of the entire photovoltaic installation. It allows you to configure the input voltage range for home appliances and personal computers or change the AC/solar charger priority settings. Additionally, the display records data and reports faults , reacting appropriately if any parameters exceed the standard. In the event of a fault, the inverter shuts down.
