COMMISSIONING / SEASONAL STORAGE PROCESS

The initial integration of the battery system with your inverter, charger or load is crucial to proper operation. DO NOT mix the Power Tower Battery with any other type of battery including other lithium, LiFePO4, SLA, GEL or flooded batteries. NEVER plug the Power Tower Batteries in series.

Initial Commissioning

Single Battery Commissioning

• If only a single Power Tower Battery is used, then no balancing or voltage check is required.
  1. Turn ON the battery master switch to ensure no errors are present
  2. Turn OFF master switch (After turning off the inverter, the breaker should be turned off first.)
  3. Connect Positive wire first
  4. Connect Negative wire
  5. Turn Master Switch ON
  6. Turn ON load
• If the battery does not output any voltage after turning on the load (inverter or other), this may be a result of a rapid capacitor charging inside the load that may be tripping the battery’s internal safety mechanism. This can be overcome by connecting a second battery in parallel to share the spike or use a pre-charge resistor.
• Certain inverters and capacitive loads may have an in rush of over 1000A on startup which may trip the internal safety cut off of the battery. To charge these capacitors and still maintain the safety profile of the battery, a pre-charge resistor can be used during commissioning. Please review the information in the following resource to match the capacitance of your load (contact inverter manufacturer): http://liionbms.com/php/precharge.php. A 100-250W resistor with a 20-50 ohm rating is recommended. Contact HPS or your local solar installer or electrician for assistance.

Multiple Battery Commissioning

1. Connect all the Batteries together via the Provided communication Wire Provided, As shown in the Customer Wiring Diagram.
2. Connect all the Positive wires to the Power Tower.
3. Connect all the Negative wires to the Power Tower.
4. Turn On each battery one by one and wait about 10 seconds after they are all on for the batteries to communicate.
5. Turn on Load.

Smart Balancing Feature

• The PT14 Battery has a smart integration system when all batteries are connected using the communication wires. This feature only integrates new battery packs when the voltage is equal to the rest of the system. This ensures no pre-balancing is required and no damage will occur to the system if unbalanced batteries were to be connected together. If during the first two cycles you notice that the display is not showing the proper number of batteries, you may have a battery that is out of balance. Rest assured that as the voltage changes when charging or discharging the system, the battery will reconnect automatically. To accelerate this process, make sure to fully discharge and charge the connected batteries.
• In extreme situations the battery that is out of balance may be severely depleted or full and it may be challenging to integrate. In this situation, charge this battery or discharge this battery to around 50% to ease integration. This can be accomplished by disconnecting the batteries that are currently on the inverter/charger and connecting the battery that is having issues to charge or discharge, then reconnecting the rest of the batteries.

Grounding
Ensure that the battery’s metal enclosure is ground to earth in a grounded system or the battery negative terminal when operating a floating system.

Seasonal or Long Term Storage
If seasonal shut down is required, please follow the below steps:

1. Fully charge battery
2. Turn OFF load and charger
3. Turn OFF batteries (After turning off the inverter, the breaker should be turned off first)
4. Store batteries in location that does not fall outside specifications including in areas where temperatures could fall below -30 °C
   Periodically check battery voltage by turning batteries ON with no load connected. Ensure voltage is above 50V. If below, batteries should be recharged.

OPERATION

Component Identification and General Operation

The system should always be left in the OFF position when not in use. In the ON position, very little power is consumed but it will affect future run times and may deplete the system over time. HPS recommends always turning the battery off when not in use.
When using the system in cold temperatures (below 0 degrees Celsius), discharge power may be limited and run time can be affected by up to 40%. The product will naturally warm itself with usage and improve capabilities. For maximum capacity and performance, ensure the battery is stored at room temperature (20 degrees Celsius).

Recharging Guide and Storage

• Charge a minimum of once every 3 month to ensure the energy level does not fall to damaging levels. If this is not possible, periodically check that the voltage is above 50V.
• Never charge above 280A. To achieve advertised life cycle, each battery pack should only be charged at <140A
• Ensure to follow integration programing guidelines if using this battery with anything other than a Power Tower.

BMS CAN BUS Capable Inverters:
When connecting an inverter that has CAN BUS and that is compatible with the batteries BMS (i.e. Solark, Victron, Schneider, etc). Connect the battery communications harness to the inverter CAN line. Depending on the system you can use the ethernet adapter and simply plug in the harness to the inverters communications port or wire the harness directly if there are only screw terminals (please refer to connector pinout in section 10). After a connection is made from battery to inverter, the inverter will need to be set up to allow for BMS control (this can vary from system to system) please refer to the inverter manual for BMS setup. Once the Inverter is set up for BMS communication, the battery will send the inverter various messages (max and min current, voltages, etc.) and the inverter will then change its setting to accommodate the battery.
