SmartECO: Intelligent Off‑Grid Cooling

A key feature of FJZ7 air conditioners, unlocked when paired with Tempra battery. SmartECO intelligently adjusts your RV air conditioner’s power use based on available battery energy—extending off-grid runtime, protecting your battery, and prioritising onboard power needs. Reliable cooling for longer, wherever you park.

The Off-grid AC Solution

SmartECO enables reliable off-grid air conditioning for the first time, by intelligently adjusting the FreshJet FJZ7 AC's cooling power based on available battery energy. SmartECO has been engineered to achieve the longest possible off-grid runtime for your air conditioning system while protecting your Dometic Tempra lithium battery. Perfect for pre-cooling your RV for when you return from a day out, or keeping your pets comfortable in the summer.

Clever Tech

SmartECO continuously monitors the Tempra battery’s state of charge while the FreshJet FJZ7 runs through a sine-wave inverter. Adjusting the compressor output, reducing cooling power, switching to fan mode, or pausing operation to manage energy use. Once battery levels recover, the system automatically restores full cooling performance. The result? Your AC running for 30% longer off-grid than before.

Features

STAY CHARGED UP.

Peace of mind is built in with SmartECO. As battery charge levels drop, SmartECO reduces A/C power to prevent deep discharge and optimise battery cycles. Meaning longer battery life and reliable off-grid cooling without unexpected shutdowns.

GET CONNECTED. ANYWHERE.

Monitor and control all functions of the FJZ7 AC from your smartphone. With WiFi connectivity for control via the Dometic Power App, switch on your air conditioner on your way back from the restaurant or beach. Comfort is always within reach.
