What Hurricanes Harvey and Irma Tell Us about Wireless Carrier Preparedness

Disclaimer: This blog is in no way meant to diminish the concern everyone at BatteryDAQ has for every living creature in the paths of these natural disasters.  We would also like to note that there exist many other ways to disrupt the power grid, both naturally and man-initiated. It is our hope and deepest desire that the effective protections against these type of events continues to improve.

If Shakespeare had penned “A hurricane by any other name is still a hurricane.”, he would have been wrong. They may all meet certain criteria that place them in the category, but the devastation they leave behind can differ, depending on their particular destructive force.

After 12 years without a major hurricane landing on the U.S. mainland, 2 significant storms have severely damaged Houston and nearly the entire state of Florida in recent weeks.  However, when we examine the impact they had on cell tower outages, they tell very different stories.

Wrong battery numbering has to be corrected

When come to substation for BMS installation, the most frequent frustration is to correct the numbering.

We have to go with standard. Wrong direction, wrong data.

Don’t worry, Sentry-6002NEMA has protection built in so the wrong direction won’t burn the board but you have to re-label all batteries as correct numbering and re-wire all cables. That may take you full day for a 60x2V string. So do check it before you start a installation!!!

Access Battery Monitoring Data with Smartphone

Using BatteryDAQ’s cloud, scan a 2D barcode on Sentry monitor or battery rack, and your smartphone will show real-time battery data and graphs.  Bank voltage, current, temperature, individual battery voltage and internal resistance etc. (SOH%, SOC% and Runtime minutes for Telecom models) are all available.

Watch your hybrid solar power

With BatteryDAQ cloud data service (FREE, if < 100 sites), you can watch your solar power remotely from anywhere with internet. This screenshot shows battery history querying for a telecom site in Arizona desert with solar panel and diesel generator. Nice batteries. 3 years of cycling now. All data can be archived in your computer if you leave Battery Analyzer software running continuously. Once a while, you may pull out data for an in-depth analysis. Don’t like our simple graph design? Just right click, dump data to Excel and plot your own beauty.

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.
