Bogart Engineering PM-5000U PentaMetric Battery Monitor/Meter Input Unit

The PentaMetric battery system monitor provides comprehensive and flexible battery monitoring for a variety of different types of battery systems which are charged by solar, wind or generators. It is intended to be most useful for systems which are regularly charged and partially discharged, rather than backup power systems that are only rarely called upon to be discharged, such as uninterruptible power systems (UPS).

The system can monitor up to two battery banks simultaneously with a common negative connection. A typical application would be to monitor a lead acid battery system with capacity of from 10 to 10000 amp hours, with system voltage from 12 to 48 volts, with one or more charging systems, such as a solar array, wind power, or generator system, and which is partially discharged daily by loads powered through an inverter. Its purpose is to provide the user with:

• Information necessary to check that the batteries and charging system are operating correctly
• To keep users informed about how much energy is in the battery system at any time
• To anticipate and identify problems before they cause a loss of service.

The PentaMetric battery monitor system offers a lot more capability than the TriMetric monitor. It measures 1 or 2 battery systems with a common negative. With one battery system, battery current plus two charging sources/loads can be measured.

The Pentametric System consists of these components:

1. Data input unit to collect, process and log data (near batteries)
2. Optional readout unit (shown above) with 2 line LCD display and control buttons. This connects to input unit with 4 wire cable up to 1000 feet away.
3. Optional computer interface with software to control and read out all data. Data may be accessed and controlled using either (or both) the optional LCD or the computer interface.

Real Time Measurement Capability

Data Logging Functions
There are 3 types of data logging functions. With the computer interface all 3 types can be output to spreadsheet file.

1. "Periodically logged data" can record any or all of the following at regular intervals: once per day to up to once per minute:
• Amp hours (3 channels)
• Watt hours (2 channels)
• Temperature max/min (1 channel)
• Volts (2 channels)
• Amps (1 channel)
• Batt%Full (2 channels)

2. "Battery discharge voltage profile" data logs volts and amps every time charge level changes by 5% (or 10%) for 1 or 2 battery systems. This checks that battery capacity is still OK--.by observing that battery voltage does not decline excessively as charge level drops.

3. "Battery cycle efficiency data" documents system efficiency for up to 2 battery systems. For each 'charge/discharge' cycle it records: cycle length (hours), total amp hours charged, total amp hours discharged, computed average 'self discharge' current and charge (amp hour) efficiency.

Controls and alarms

Relay output
Control external relay to go on and off at specified voltage levels and/or %battery state of charge levels. "On" and "off" levels can be independently set.

Audible and visual alarms
Has audible or visual signal for 'Low voltage or low state of charge', 'High voltage', 'battery is charged', 'too many days since charged', and 'too many days since equalized'.
