The MHT-20K-40 is a three-phase hybrid inverter designed for large homes and commercial operations. It offers 20 kW of power , up to 98.4% efficiency , two MPP trackers with 30 A input current and 40 A charge/discharge current . With intelligent fan cooling, high reliability and advanced connectivity options (WiFi, LAN, RS485, CAN), the MHT-20K-40 provides a cutting-edge solution for efficient, secure and intelligently managed energy.
Efficient use of solar energy
The MHT-20K-40 inverter delivers 20 kW of power and a maximum efficiency of 98.4% , which guarantees excellent utilization of solar energy in larger installations. Thanks to two MPP trackers and an extended MPPT range of 200–950 V , it can effectively optimize production even in non-ideal conditions on the roof. 30 A input current per tracker ensures reliable operation even at higher powers.
Backup and quick switch to UPS mode
The MHT-20K-40 model supports charging and discharging currents up to 40 A and automatically switches to UPS mode within 10 ms in the event of a power outage, protecting your appliances from power outages. The backup output provides a full 20 kW of power and up to 33.5 A of output current , which is ideal for larger homes, commercial buildings or smaller operations with high demands.
Safety, quiet operation and easy control
The inverter is equipped with intelligent fan cooling and, despite its higher power, maintains noise levels below 40 dB , which guarantees quiet operation. It offers WiFi, LAN, RS485 and CAN interfaces , making it easy to integrate into any system and conveniently controlled via the app. All protection functions – from overvoltage to short circuit – are integrated , ensuring maximum safety in every use.
Easy control via mobile app
Smart mode is fully accessible directly through the app , where the user selects the country, sets limits, strategies and preferences for purchasing and using energy. In the app, you can choose from three strategies – by percentage difference, by specific price or by duration of the most advantageous time zones. Everything works automatically , while the user has an overview of planned and current savings .
Intelligent response to fluctuating electricity prices
Solinteg Smart Mode allows the MHT-20K-40 inverter to automatically optimize energy consumption and storage based on current electricity prices. It uses a strategy of purchasing energy during times of low prices and selling or using stored power during high prices. This system helps reduce electricity costs, maximize solar energy utilization, and increase overall household efficiency. Smart Mode is especially ideal for areas with dynamic electricity prices, including Slovakia.
