The T80 Charge Controllers integrate maximum power point tracking, battery charge management, state-of-charge information and communications into a single device. The T80 can deliver 80 amps continuous output to 12-, 24-, 36 or 48-volt battery systems from PV arrays with open circuit voltage up to 140 VDC (150 volts absolute maximum voltage). The new T80HV allows you to wire modules in series up to 200 Voc max/160 volts nominal.
The T80 and T80HV produce full-rated power without de-rating up to 45 degrees C/113 degrees F ambient temperature. Above that, the output current is reduced gradually to protect the life of the T80, and then automatically ramped up as the temperature decreases. High efficiency power circuits and robust thermal design minimize heat generation. The internal temperature-controlled variable speed fan runs just fast enough to maintain optimum reliability. UL Listed. Dimensions are 15.2" x 8.5" x 4.4" and weight is 22 lbs.
Both controllers include a built-in energy monitor using TriMetric technology from Bogart Engineering. The monitor tracks energy production and consumption to calculate the energy remaining in the battery. State of charge (SOC) is displayed in percent of capacity, amp-hours, watt-hours, and bar-graph format. They store 90 days of energy-harvest history and feature a slot for add-in cards providing system performance, data communication, and firmware updates.
Controllers do not include shunts. Order a 500A/50mV shunt if your system doesn't have one. Both the T80 and T80HV support flooded lead acid (FLA), GEL and absorbed glass mat (AGM) batteries. Two independently programmable SPST relays can be used to control external devices based on battery voltage, charge or discharge current or battery state of charge. Contact rating is ½ amp at up to 50 VDC.
An optional wired display is available. The RD-wired display can be up to 100 feet from the controller using 4-conductor telephone cable.
