The T80 TurboCharger integrates maximum power point track-ing, battery charge management, state-of-charge information and communications into a single device. It can deliver 80 amps continuous output to 12-, 24- or 48-volt battery systems from PV arrays with open circuit voltage up to 140 VDC (150 V absolute maximum voltage). Wire modules in series to use smaller wire between the array and charge controller. The T80 captures up to 35% more power from the PV array. Their MPPT algorithm starts early and locks onto the peak power during rapidly changing insolation and temperature. The controller supports flooded lead acid (FLA), GEL and absorbed glass mat (AGM) batteries. Four-stage charging with adjustable set points for all parameters.

     The T80 TurboCharger produces full rated power without de-rating up to 40oC 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.

     The T80 includes a built-in energy monitor using TriMetric technology from Bogart Engineering. It tracks power produc-tion and consumption to calculate the energy remaining in the battery. State of charge (SOC) is displayed in percent full, amp-hours, watt-hours and bar graph format on a 4-line 20-character LCD with back light. In addition, 90 days of energy harvest history is stored in the T80. The on-board RS-232 and slot for optional add-in cards provide data communication to remote readouts, PCs and the internet. System performance can be monitored remotely and the T80 accepts software upgrades from a PC.

     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.

     Optional wired and wireless displays are available. The RD wired display can be up to 100 feet from the con-troller using 4-conductor telephone cable. The RD100 wireless display can be 100 feet away from controller in buildings and 300 feet line-of-sight. Its built-in rechargeable batteries last up to 3 months and can be recharged from 12, or 24 VDC or 115 VAC.

     Optional network card allows you to stack up to 16 T80 controllers on one battery bank. Add a network card to each controller and connect with CAT-5 cables. One con-troller acts as a master and the others as slaves.
