GTIS Power and Communications Systems
Description
What this product does: The OutBack FLEXMax MPPT charge controller is a voltage regulator that keeps your batteries from being over charged by your solar panels.
Recommended use(s): FLEXMax charge controllers allow you to string solar panels in series, up to 150 V, to charge battery banks of 12 V to 60 V. GTIS recommends using a 48 V battery bank whenever possible.
Advantages of this product: The OutBack FLEXMax is a sophisticated MPPT (maximum power point tracking) charge controller that will automatically find and track the maximum power point of your solar panels and charge your batteries with three-stage charging (bulk charge, absorption and float) and temperature compensation. With the FLEXMax you can use several solar panels in series, up to 150 V, to charge a battery bank of any lesser voltage from 12 V to 60 V.
It has a four-line LCD display screen to show various statuses and faults, and to facilitate programming of its many operational parameters. The last 128 days of operational data (Amp-hours, Watthours, time in float, peak Watts, Amps, solar array voltage, maximum battery voltage, minimum battery voltage and absorb time, accumulated Amp-hours, kWh of production) are logged for review.
Disadvantages of this product: The low battery disconnect is intended to operate a relay to turn off auxiliary loads and save battery capacity, but does not control the main load directly.
Additional notes: The 80 Amp version of the FLEXMax has a cooling fan, but is otherwise the same as the 60 Amp version.
