  • Page 23 • Do not install in locations where water can enter the controller. • Loose power connections and /or corroded wires may result in resistive connections that melt wire insulation, burn surrounding materials, or even cause fire. Ensure tight connections and use cable clamps to secure cables and prevent them from swaying in mobile applications.
  • Page 24 • Stranded wires to be connected to the ProStar MPPT terminals should be prepared first with e.g. clamped copper heads, etc. to avoid the possibility of one conductor free out of the connection screw, and possible contact with the metal enclosure. WARNING: Solar and battery fuses or DC breakers are required in the system.

    3.3 Mounting Inspect the controller for shipping damage. Mount the ProStar MPPT to a vertical surface (4-#8 stainless steel self-tapping screws are included). Tighten the mounting screws, using care not to crack the plastic case. Do not install directly over an easily combustible surface since the heat sink may get hot under certain operating conditions.

  • Page 30 STEP 1: Check Controller Limitations Verify that the highest temperature compensated solar array open-circuit voltage (Voc), and load current do not exceed the ratings of the ProStar MPPT version being installed. Multiple controllers can be installed in parallel on the same battery bank to achieve greater total charging current.
  • Page 31 the true battery voltage would only be 14.1 volts, if there is a 0.3 volt drop between the controller and battery. Note that the battery sense wires will not power the controller, and the sense wires will not compensate for losses in the power wires between the controller and the battery.
  • Page 32 STEP 3: Remote Temperature Sensor WARNING: Risk of Fire. If no Remote Temperature Sensor (RTS) is connected, use the ProStar MPPT within 3m (10 ft) of the batteries. Internal Temperature Compensation will be used if the RTS is not connected. Use of the RTS is strongly recommended. AVERTISSEMENT: Risque d'incendie.

A 12 volt battery bank can be charged with a 12, 24, 36 or 48V nominal off-grid solar array. Certain grid-tie solar modules may also be used as long as the solar array open circuit voltage (V ) rating will not exceed the...

  • Page 41: Battery Charging Information

    4.2 Battery Charging Information 4-Stage Charging The ProStar MPPT has a 4-stage battery charging algorithm for rapid, efficient, and safe battery charging. Figure 4-2 shows the sequence of stages. BULK NIGHT FLOAT ABSORPTION NIGHT CHARGE TIME Figure 4.2. ProStar MPPT Charging Algorithm Bulk Charge Stage During Bulk charging, the battery is not at 100% state of charge and battery voltage has not yet charged to the Ab-...
  • Page 42 The battery must remain in the Absorption charging stage for a cumulative 120 - 150 minutes, depending on battery type, before transition to the Float stage will occur. However, Absorption time will be extended by 30 minutes if the battery discharges below 12.50 volts (12V system) the previous night.
  • Page 43 Equalization Stage WARNING: Risk of Explosion Equalizing vented batteries produces explosive gases. The battery bank must be properly ventilated. CAUTION: Equipment Damage Equalization increases the battery voltage to levels that may damage sensitive DC loads. Verify all system loads are rated for the temperature compensated Equalize voltage before beginning an Equalization charge.
  • Page 44 battery voltage above the standard absorption voltage so that the electrolyte gases. The green SOC LED will blink rapidly two (2) times per second during equalization charging. The duration of the equalize charge is determined by the selected battery type. See table 4-1 in this section for more details.
  • Page 45 When to Equalize? The ideal frequency of equalizations depends on the battery type (lead-calcium, lead-antimony, etc.), the depth of discharging, battery age, temperature, and other factors. One very broad guide is to equalize flooded batteries every 1 to 3 months or every 5 to 10 deep discharges. Some batteries, such as the L-16 group, will need more frequent equalizations.
  • Page 46 the “boost” cycle for sealed cells can be disabled by setting the equalize setting switch to manual, if required. Battery Charge Settings Preset ProStar MPPT battery charging options are shown in tables 4-1 and 4-2 below. All voltage settings listed are for nominal 12 Volt batteries.
  • Page 47 The ProStar MPPT provides seven (7) standard battery charging settings that are selected with the settings switches (see Table 4.1 above). These standard charging settings are suitable for lead-acid batteries ranging from sealed (gel, AGM, maintenance-free) to Flooded and L-16 cells. In addition, an eighth charging setting provides for custom set-points using MSView PC software.

Float Exit Time-out Charging Profile After entering Float stage, the controller will only exit Float if the battery voltage remains below Float voltage for 60 cumulative minutes.
  • Page 49 Float Cancel Voltage Figure 4.5. Float Cancellation Charging Profile If the battery bank discharges below 12.30 volts (24.60 volts @ 24 V) the previous night, Float charging stage will be cancelled for the next charge cycle. Figure 4-5 above, illustrates this concept. At 0:00 hrs (dawn), battery voltage is below the Float Cancel threshold voltage.
  • Page 50 Equalize Time-out Figure 4.6. Equalize Time-out Charging Profile The charging profile in figure 4-6 above, shows an Equalize Timeout event. The timeout timer begins as soon as battery voltage exceeds the Absorption voltage setpoint. If there is insufficient charging current or system loads are too large, the battery voltage may not reach the Equalize setpoint.

  • Page 51: Load Control Information

    4.3 Load Control Information The primary purpose of the load control function is to disconnect system loads when the battery has discharged to a low state of charge and reconnect system loads when the battery is sufficiently recharged. System loads may be lights, pumps, motors, DC appliances, and other electronic devices.
  • Page 52 The amount of time between a green SOC indication and load disconnect will depend on many factors including: • rate of discharge (amount of load draw) • capacity of the battery • health of the battery • LVD set-point If the battery discharges to the LVD set-point the load will disconnect and a solid red Battery Status LED indication will be displayed.

    NOTES: 1) R flashing is generally a user addressable fault / error 2) R charging status LED ON with heartbeat blink OFF every 5 secs is a critical fault that generally requires service. See, "Solid Charging Status LED with Self-test (R-Y-G) SOC Faults", in Section 5.1.

  • Page 64 disconnected. A small overload could take a few minutes to disconnect. The ProStar MPPT will attempt to reconnect the load two (2) times. Each attempt is approximately 10 seconds apart. If the overload remains after two (2) attempts, the load will remain disconnected until power is removed and re-applied.
  • Page 65 can be used to determine if the RTS is working properly. Battery Sense Cables Issue Error status LED: Flashing red. Battery status LEDs: R/Y - G/Y sequencing. If a fault in the battery sense connection (such as a short-circuit, open circuit or loose terminal) occurs after the battery sense has been working, the LEDs will indicate a failure.
  • Page 66 Battery Over-Current Error status LED: Flashing red. Battery status LEDs: R/Y-G sequencing. While rare, if battery charging current exceeds approximately 130% of the controller’s output current rating, this fault can occur. The fault is generally related to fast, large battery voltage transients (connecting a very heavy or capacitive load like an inverter) that are faster than the controller can regulate and it shuts off to protect the circuitry.
