Simple, but it has a brain
Sentry-NB8 has been chosen for many telecom carriers worldwide including recent order of 100 units from South Africa.
This unit has been tailored to cell towers or micro sites with 8 batteries, 2 strings of 4x12V. Separate harness goes to each string for quick and clean installation. Unit automatically accepts 1 or 2 current transducers so no surprise when come to a site for retrofitting.
It is more than a data collector for voltage, current, temperature and internal resistance. It faithfully processes the data and even with machine learning to achieve high accuracy estimation for SOH (state-of-health), SOC (state-of-charge), total runtime and remaining runtime, plus thermal risk level. Ethernet port provides remote web access to battery data and Modbus-TCP integration. Plug and play, compatible with MyBattery Platform to manage unlimited number of sites. (Really, 100,000+ sites on your big screen.)
Two dry contacts for urgent and service alarms. No more extra ports or functions. It is simple.
