For safety purposes, these instructions must be followed during installation, operation and maintenance of the GenStar MPPT solar controller. The following symbols are used throughout this manual to indicate potentially dangerous conditions or mark important safety instructions: WARNING: Indicates a potentially dangerous condition.
  • Page 7 WARNING: Shock Hazard This unit is not provided with a GFDI device. This charge controller must be used with an external GFDI device as required by the Article 690 of the National Electrical Code for the installation location. • Mount the GenStar MPPT indoors. Prevent exposure to the elements and do not allow water to enter the controller.
  • Page 8 • Determine if battery is inadvertently grounded. If so, remove the source of contact with ground. Con- tact with any part of a grounded battery can result in electrical shock. The likelihood of such a shock can be reduced if battery grounds are removed during installation and maint enance (applicable to equip- ment and remote battery supplies not having a grounded supply circuit).

    Generally accepted wiring practice is to limit voltage drops between the charger and the battery to 2%. Even properly sized wiring with 2% drop can result in a 0.3 volt drop for 14.4V charging. Voltage drops will cause some undercharging of the battery. The controller will begin Absorption or limit equalization at a lower battery voltage because the controller measures a higher voltage at the controller’s terminals than is the actual battery voltage.

  • Page 24: Installation

    Lithium batteries do not require temperature compensation. Therefore, temperature compensation is disabled for all of the GenStar MPPT lithium battery presets. However, if the lithium battery temperature drops below freezing or becomes very hot during charging, it can cause irreversible harm to the battery. Therefore, where the battery temperature can get excessively low or high, it is important to use the low or high temperature foldback settings together with an RTS.

    5.2.2 Charging Profiles GenStar MPPT offers eight (8) preset battery charging profiles, as seen in Tables 5-1 below. These standard charging settings are suitable for lead-acid batteries ranging from sealed (gel, AGM, maintenance-free) to Flooded and Lithium cells. All voltage settings listed are for nominal 12 Volt batteries. Multiply the voltage settings by two (2) or (4), for 24 and 48 Volt systems, respectively.

Absorption Extension Charging Profile If battery voltage discharges below the Absorption Extension Threshold the previous night, Absorption charging will be extended on the next charge cycle as shown in the example in Figure 5-3 above.
  • Page 61 Float Exit Time-out Voltage Threshold Figure 5-4. Float Exit Time-out Voltage Charging Profile In Figure 5-4 above, the Float Timeout is set for 60 min. A system load turns on at 3:30 hrs during the Float stage and runs for one hour, then turns off at 4:30 hrs. During this time the load current draw is higher than the charge current so there is a net discharge causing the battery voltage to drop.

  • Page 62: Load Control Information

    For Lead-acid presets, the battery bank discharges below 12.0 volts (24.0 volts @ 24 V) the previous night, Float charging stage will be cancelled for the next charge cycle. Figure 5-5 above, illustrates this concept. At 0:00 hrs (dawn), battery voltage is below the Float Cancel threshold voltage. The diagram shows where Float stage would have occurred if Float was not canceled.
