Invertor ORVALDI MVII5K 5 kVA / 5 kW s MPPT a 4 kW PV vstupom

ORVALDI MVII5K 5 kVA / 5 kW with MPPT and 4 kW PV input is a hybrid grid-tied and standalone power inverter designed for residential and small commercial solar systems. It combines power conversion, battery charging and integrated MPPT solar charge control in a single unit, enabling AC output, PV input management and battery interaction. The inverter supports continuous 5 kW output power and accepts up to 4 kW of photovoltaic input for efficient energy harvesting and backup operation.

Advantages

The inverter integrates MPPT solar charge regulation with inverter functions, reducing component count and simplifying installation. It provides stable sine-wave AC output suitable for household appliances and small commercial loads, and supports battery charging and discharge coordination for backup and peak-shaving scenarios. The device is engineered for reliable power conversion with features that help optimize self-consumption of solar production while enabling automatic transfer between grid-tied and off-grid modes when configured.

Suitable for

• Residential solar systems with battery backup
• Small commercial installations requiring up to 5 kW of inverter capacity
• Off-grid or hybrid installations where PV input and battery management are needed
• Applications requiring uninterrupted AC power during grid interruptions

Key specifications

• Continuous output power: 5 kW (5 kVA)
• Integrated solar MPPT charge controller supporting up to 4 kW PV input
• Hybrid operation: grid-tied and standalone (off-grid) capability
• Sine-wave AC output suitable for standard household and commercial loads
• Battery charge/discharge management and backup support

How to use

Install the inverter according to local electrical codes and the manufacturer’s installation instructions, ensuring correct AC grid connection, PV array wiring and battery bank connections. Configure system parameters such as charge current limits, grid/backup priorities and MPPT settings through the inverter’s interface or configuration tool. During normal operation the unit will convert PV and battery energy to AC output, manage battery charging from PV and grid as configured, and provide automatic switchover to backup power when grid supply is interrupted.

Recommendations

Position the inverter in a well-ventilated, dry location away from direct sunlight and corrosive environments. Size PV array and battery capacity to match expected loads and backup duration; ensure protective devices (AC breakers, DC fuses, surge protection) are installed. Regularly inspect AC and DC connections and keep firmware updated to maintain safe and efficient operation.
