MY-PV AC ELWA-F Frequency Responsive Solar Immersion Heater

For use in off-grid systems to use surplus energy once a battery has become fully charged.

The ELWA-AC-F detects frequency rise of the inverter, if there is excess energy available and uses it for heating water.

Advantages

• AC ELWA-F uses energy that cannot be stored in the battery
• Linear power control 0 - 3.000W for maximum self-consumption
• The AC ELWA-F needs no communication cables to the inverter
• Sinusoidal current consumption (no thyristor)
• For AC off-grid systems with frequency-shift inverters eg. Sunny Island & Victron
