Registration: Deployment Details

There is a QR code on the battery that says “Registration” and includes the unique serial number for the device.
Please complete the questions on this form as it will help with any troubleshooting in the future. If you have the data monitoring service, this will allow us to more accurately estimate the power production capability of the system.

Battery Operation

      Turn Battery On / Off

      The battery is shipped with the output power disconnected. To turn the battery on and activate the output, connect the output cable. The pins [X] and [Y] are connected and complete the circuit with our charge controller, activating the output.

      [image pins connected]

      [image cable connected to output]

      Disconnect the output cable to turn the battery off.

Charge Battery

      Battery will charge when the solar panels are connected and the solar panels are outside. Connect the MC4 cables firmly into the matching MC4 cables on the battery to create a waterproof connection.

      [Drawing of panel connected to battery]

      Voltaic also has an optional AC/DC charger. Charge times will vary. [Light on charger changes from X to Y when full].

Indicator Lights

      The internal charge controller has a few lights that can help us understand the battery status.

      • LED 2: Red / Green / Flashing
      • LED 3: Red / Green / Flashing

Other Battery Tests Pre-Deployment

      Pre-deployment, you can get an accurate reading of the battery charge level by using a multimeter on the battery output. You should see a voltage between X and Y. Remember that a cable must be connected to the output to activate the battery.

      You can also connect a charge cable to your device and confirm that it turns on.

Charge Circuit Description

      The battery contains an MPPT charge controller. When connected to a solar panel, the controller will search for the panel voltage with the highest power.

      The battery will charge until it reaches the cutoff voltage, [slow down to Y] and then shuts off at battery [shuts off] / [tapers].

      The charge controller also contains a number of protections, including short circuit, over discharge, high temperature and low temperature.

Battery Cutoffs and Reactivation

      The battery has a number of safety features to prevent damage from the battery.

Battery Charge & Discharge Curve


Optional Connectors


      To activate the output, you need to connect the cap to the M14 connector. This connects Pin X & Y and turns on the charge controller.

      Connect your device to the PoE port and it should turn on.

      [Image of device connected to PoE connector]

      The PoE injector consumes approximately 0.5 Watts continuously so do not connect for an extended period of time until you are ready to deploy.


Monitor Battery During Deployment

      Monitoring the battery can help determine the health of the system, likelihood of an outage and timing of a replacement. There are a few ways to monitor the battery.


      The 12V battery output is unregulated. Time series data of the voltage will reveal important data including the low voltage of the day. This shows the depth of discharge.

RS Feed

      This must be specified in advance of purchase. Voltaic can modify the waterproof case so that the RS Feed of the charge controller passes through the case.

      The following information is available from the charge controller: battery voltage, battery current, load voltage, load current, solar voltage, solar current, temperature, power control switch.

      Details are available

Voltaic IoT Module

      Voltaic’s IoT module reports battery health data to a pre-configured dashboard.

      If you purchased this option, there will be a QR code on your battery with the label “System Monitoring.”
