Inverters provide the necessary power for emergency lighting if utility power is unavailable. Isolite inverters charge battery banks from utility power, discharge batteries to generate power in an emergency, and then transfer back to the utility power when available. Inverters also monitor the state of the utility power, automated code compliance and are more cost-effective than other solutions. Isolite offers small, medium, and building-scale inverters.

The Isolite E3MAC3P is a 3,000 – 18,000 VA three-phase modular AC inverter. It has a programable and password-protected user interface, allowing for optional web monitoring. It is 98% effective for minimal BTU losses and has a PWM Inverter that provides pure sine wave output with less than 3% THD. The programmable transfer time feature can be changed between standard and fast transfer times for better load and site compatibility. The crest factor has >4 overload protection for demanding high in-rush loads. The UL is listed for a 90-minute run-time and is compatible with all light loads, including HID. It has a variable time delay, three-phase output, and a startup diagnostic that checks to see if it was correctly installed.
