The EIBIM is an upgrade to our former EIIM.
What makes this system unique as against former versions includes the following:
1. This one has an inbuilt transformer for its own regulated power source unlike the former models that depended on Inverter battery for operational power.
2. It has an independent input for inverter battery voltage monitoring
3. (I like this part!) It has a digital DC Voltmeter that makes it easy for you to actually monitor voltage levels…both the preset threshold voltage level (No more guess work!) and the actual inverter battery voltage level at any given time.
4. It has four (4) status indicators, informing you at all times the current operational status of the EIBIM.
5. It has a switch through which you can choose which voltage level you want to monitor (a) Preset threshold level, while adjusting (b) Current Inverter battery voltage level.
6. Digital TIMER with display for charge duration setting
