High-Performance Three-Phase Solar, Battery and Backup Solution

The Solinteg MHT-10K-40 belongs to the Integ M three-phase hybrid inverter series. Solinteg positions the MHT 10–20kW range as a high-voltage three-phase hybrid platform supporting solar generation, battery storage, intelligent energy management and backup power.

The 10kW model supports a maximum PV array size of 16kWp, two MPPTs and up to 30A input current per MPPT, giving installers more flexibility for modern higher-power solar modules and larger PV arrays.

Key Features

☀️ Up to 16kWp Solar PV Capacity

The MHT-10K-40 supports a maximum PV array power of 16kWp, giving the 10kW inverter additional PV sizing flexibility for larger solar installations.

The official Solinteg product page also highlights high-power PV support, including 30A PV input current capability for the MHT 10–20kW series.

40A High-Power Battery Charging and Discharging

The inverter supports:

Maximum battery charge current: 40A
Maximum battery discharge current: 40A
Maximum battery charge power: 10kW
Maximum battery discharge power: 10kW

Solinteg describes the 40A charge/discharge capability as supporting efficient and rapid energy transfer.

⚡ Wide High-Voltage Battery Range

The MHT-10K-40 supports compatible lithium-ion battery systems operating across a wide 135–750V range.

This wide high-voltage battery range gives system designers flexibility when selecting compatible battery configurations.

Fast Backup Switching

The inverter supports an on-grid to off-grid switching time of:

Less than 10 milliseconds

This helps maintain continuity for supported backup circuits during a grid interruption, subject to system configuration and compatible backup loads.

Powerful Backup Performance

For the MHT-10K-40, the backup side specifications include:

• 10kW rated backup output
• 18kVA peak apparent output for 10 seconds
• <10ms switching time

Solinteg highlights the series as supporting up to 180% overload capability during outages, depending on the model and operating conditions.

⚖️ 110% Unbalanced Three-Phase Output

The MHT series supports 110% unbalanced output capability, helping manage uneven loads across three phases.

Solinteg highlights this capability as supporting more flexible load distribution and improved self-consumption in three-phase applications.

IP65 Protection

The MHT-10K-40 has an IP65 ingress protection rating and is designed for suitable indoor and outdoor installation environments in accordance with the manufacturer's installation requirements.

Intelligent Energy Management

The 2026 datasheet highlights a range of smart energy management capabilities across the MHT series, including:

• six work modes;
• Time-of-Use energy strategies;
• dynamic pricing strategies;
• user-defined scheduling rules;
• peak-shaving control based on configurable thresholds;
• centralised smart management;
• remote upgrades;
• OLED and app-based control;
• Solinteg I-light status indication.

These capabilities can support better coordination of solar generation, battery charging and discharging, grid import and backup operation, depending on system configuration and energy tariffs.

Technical Specifications

The datasheet notes that PV maximum input voltage depends on battery connection conditions, so installation design should follow the manufacturer's technical limits and installation requirements.

Integrated Protection Features

The MHT-10K-40 datasheet lists integrated protection functions including:

• DC reverse polarity protection;
• battery reverse connection protection;
• insulation resistance protection;
• DC and AC Type II surge protection;
• over-temperature protection;
• residual current protection;
• anti-islanding protection;
• AC over-voltage protection;
• overload protection;
• AC short-circuit protection.
