The OFF-GRID PWM3KW50A Solar Photovoltaic Inverter from AGM is a multifunctional standalone device in the "Energy Independence > Inverters" category, combining an inverter, a PWM-based solar charger, and a battery charger, with WiFi connectivity for monitoring and configuration.

This inverter is designed to provide stable power to household and small industrial loads in grid-tied mode or autonomously from batteries and solar panels. The device is suitable for systems where reliability, ease of integration, and remote control capabilities are important. Below are detailed technical parameters to help assess the inverter's suitability for your needs.

Technical Data

Grid Mode

• Input voltage waveform – sine wave (from grid or generator)
• Nominal input voltage – 230V AC
• Low voltage disconnect – 170V AC (UPS), 100V AC (typical electrical devices)
• Maximum AC input voltage – 300V AC
• Nominal input frequency – 50 Hz / 60 Hz (auto-sensing)
• Output short-circuit protection - grid mode: overcurrent protection; battery mode: electronic protection
• Transfer time – 10 ms (typical UPS); 20 ms (typical – electrical devices)
• Output power derating – when input voltage drops below 170V AC, output power is limited

Inverter Mode

• Nominal output power – 3kVA / 3kW -3000W
• Output voltage waveform – pure sine wave
• Nominal output voltage – 230V±5%
• Output frequency – 50 Hz
• Peak efficiency – 90%
• Instantaneous peak power – 2x nominal power for 5 s – 6000W
• Nominal DC input voltage – 24 VDC
• Cold start DC voltage – 23 VDC
• Self-consumption –

The OFF-GRID PWM3KW50A inverter from AGM stands out for its easy connection and versatile application: it is suitable for off-grid solar stations, backup power for residential premises, country houses, small offices, and facilities where a stable sine wave output is crucial. The built-in PWM controller ensures efficient battery charging from photovoltaic modules, and cold start support from 23V DC guarantees startup even with discharged batteries.

The device features short-circuit and overload protection, automatic 50/60 Hz frequency detection, and output power limitation when the input voltage drops below a critical level. The inverter's peak capabilities (up to 6000W for a short time) allow it to start inductive loads such as compressors or electric motors, and the pure sine wave ensures safe operation of sensitive electronics.

Brand: AGM. Product type: Energy Independence > Inverters. Model: OFF-GRID PWM3KW50A PWM 3 KW + WiFi.

This inverter will be a reliable component of your power supply system, offering a balance between power, efficiency, and remote monitoring via WiFi. Before installation, it is recommended to consider the nominal voltage values and peak currents to ensure compatibility with the load and battery bank.
