T80 Turbo Charger
The T80 TurboCharger integrates maximum power point tracking, 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 derating 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 production and consumption to
calculate the energy remaining in the battery. State of charge (SOC) is
displayed in percent full, amphours, 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 controller 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 controller acts as a
master and the others as slaves.
