More Info

The IOTA IQ4-40-HOUR smart controller is engineered to meet the demands of large-capacity flooded lead-acid battery banks, delivering reliable and efficient charging.

It employs IOTA’s proven 4-stage charging algorithm, including an extended bulk stage to ensure full battery recharge before transitioning to absorption and float stages.

The float stage maintains batteries at 13.6 volts to prevent gassing while preserving charge, and a maintenance mode refreshes the battery every seven days to prevent stratification and extend battery life.

This controller is especially beneficial in systems where short bulk charging cycles fail to fully recharge batteries, such as solar and generator-based setups.

Installation is simple with plug-and-play compatibility for IOTA DLS chargers ranging from 15 to 90 amps, making integration seamless.

An LED status indicator provides clear visual feedback on charging stages and system status for easy monitoring.

Weighing approximately 0.5 pounds, the compact design allows for convenient placement in various installation environments.

IOTA Engineering, based in Tucson, Arizona, has over 40 years of experience delivering high-performance power conversion and battery charging solutions trusted across solar, RV, telecom, and emergency power sectors.

Our knowledgeable team is available to assist with product details, installation advice, and purchasing guidance to ensure you select the right charging solution for your needs.
