This guide is designed to help you maximize your unit’s autonomy and extend your battery’s life. Through optimal deployment and maintenance of your solar panels and batteries, you can get the most out of your unit.
We’ve rounded up all the steps needed to achieve maximum performance. See the videos or read the detailed guide below!

1.1. Batteries & solar panels
First, a quick reminder: all our units run on deep-cycle batteries and are equipped with solar panels that maintain the battery voltage of your unit (they do not fully charge the unit). The number of batteries and the type of solar panels (flat vs. tilted) are determined by solar calculations according to the geography and climate where the unit will be used.
See how to determine performance and best position your solar panels below.

1.2. How to ensure your solar panels are performing normally
To make sure that your solar panels are charging your batteries, on a sunny day, check that the solar amperage is higher than the battery amperage. You can find this information on your unit’s controller.

To maximize the solar energy being absorbed by the panels, you must, if possible, have them tilted to:
1.3. Solar regulator
Our units are equipped with a solar regulator that controls the amount of power that is supplied to the batteries for charging, as well as the power required for the unit to function.
This regulator is also equipped with a Low Voltage Disconnect (LVD) feature that acts as a safeguard to protect your batteries by shutting down the unit if needed. The LVD feature will activate if your battery voltage drops below 10.4 volts, and can only be deactivated when you recharge the batteries past 12.6 volts.

Figure 4 - Solar Regulator |
Any time a unit drops below the 12-volt range, and/or the regulator goes into LVD mode, it is recommended to recharge the batteries to avoid damage caused by them draining completely (for charging information, please refer to Section 5. Auxiliary outlet charging).
2.1. Charge your batteries
Prior to any deployment, charge your batteries and ensure they are charged above 12.6 volts. You can view this information on the home screen of your V-Touch Controller. You can also use a load tester to confirm if the batteries are in functioning condition. Please look at the instructions from the load tester manufacturer to know how to proceed with the test.

2.2. Deployment: position away from sources of shade
Where you deploy your unit will directly affect its autonomy. This step is extremely important. When deploying, always position your equipment in an area of your work zone that will not be affected by shade (near trees, overpasses, buildings, the unit’s mast,etc.).This will allow solar panels to receive as much direct sunlight as possible. Failing to properly deploy your unit will cause the batteries to drain slowly, as they will not receive enough solar voltage to maintain them.
2.3. Steps to follow when deploying a Ver-Mac unit
When deploying your unit, please follow these steps:
1. Ensure the unit is on solid, levelled ground with jacks properly deployed.
2. Raise sign just above the cradles, angle it towards oncoming traffic, and lock it using the hand break.
3. Release the solar panel’s hand break. Raise & tilt solar panel.
4. Solar panel tilting:
5. Raise the sign to desired height and insert the mast’s safety D pin in place.

Once your unit is deployed, it is important to ensure proper maintenance of the solar panels and batteries for your equipment to run as efficiently as possible.

When checking the voltage, it is normal to see drops for the solar portion, as the solar panels will not capture energy at night. The battery voltage will remain relatively stable if everything is functioning as it should.
3.1. Set up a voltage alert in JamLogic
Our JamLogic software allows you to set up battery alerts.
Before setting up an alert, you will need to create a mailing list. In JamLogic, press Tools, then Mailing Lists Editor.
In the Mailing Lists Editor screen, you will have the ability to create different groups and add user emails. In the example below, the default group has 1 email address. This email will receive the alert once it is triggered. You may add multiple emails to that list. Click Save when ready.

Next, you will need to go to Tools, then Alerts Manager. You will be brought to the Alerts Manager window. In this window, you can press Add and select Battery Trend in the dropdown menu.

Battery trend is an alert that will analyze the last ten days of your battery’s state of charge and compare it to the previous three days. If the algorithm detects a change in the battery voltage, it will trigger an alert.

Once your alert is set, you must select the devices for which you want an alert. Click on Devices, then double-click on the unit you wish to add the alert on. Press OK, then save when you are finished and the alert icon will appear.

This new feature will give you much more accurate and reliable information on the state of charge of your batteries. It will also allow you to be more proactive if the batteries need to be changed or charged.
If you experience power issues, the solar regulator is the primary resource to identify the issue. The LEDs on the regulator will inform you of the state of the batteries, as well as their charging status.
4.1. See the state of charge
When charging the unit, you can refer to the LEDs on your regulator (see figures below) to see the charging status.
Please note that we now have a next-generation regulator. Your unit may have a first-generation solar regulator, or a next-generation solar regulator. Please refer to the images below to see which one you have and how to proceed with your model.

4.2. Using a voltmeter
You can also get the voltage readings by using a voltmeter. You will be able to see the battery & solar voltage as well as the output going to the sign.
Our solar regulators are equipped with two 30-amp fuses. The top is a spare while the bottom one is live.
It is important to note that your battery voltage & output readings must be just about identical. If you are getting a low output voltage, the regulator could be defective.
With a first-generation solar regulator, you can get the voltage by attaching the voltmeter to the metal brackets. Please follow the grid below.

To measure voltage with a next-generation solar regulator, place the voltmeter probes in the empty spaces above the wires. Please follow the grid below.

When your unit has low batteries, you can use the onboard charger to recharge your unit. Most Ver-Mac trailers are equipped with an IOTA charger with an additional IQ4 module. By plugging the charger into a 110V AC outlet, your unit will slowly begin charging.

You can use the following table to view the charging status of your IQ4 smart charger.

Figure 22 - IQ4 LED Indicators |
Note: The IQ4 module allows the charger to charge in Bulk and Absorption modes for a 24-hour period only. This time limit is set to prevent overcharging, which could damage your batteries. As a result, when the battery level is too low, the charger may not be able to fully recharge the battery pack in a single 24-hour period. When the 24-hour time limit is up, the IQ4 LED (small green light) stays ON continuously and the IQ4 needs to be reset.
For recommended recharging times, please refer to the charts below.

Batteries perform best in the first three years. If well maintained, they can last up to five years.
It is important to check the charge of your batteries before and after winter to identify which batteries need to be charged and which ones are defective & must be replaced.
6.1. INDOOR STORAGE
If possible, keep your unit on a charger throughout the winter to prevent the batteries from draining.
a. If your unit has a first-generation solar regulator (see image below): disconnect the red connector on your solar regulator to prevent the batteries from draining.

Figure 26 - First-generation solar regulator |
b. If your unit has a next-generation solar regulator (see image below): Same steps apply as with the first-generation regulator, except that on point 2.a, you will need to disconnect the red (Batt +) and black (Batt -) connectors leading from J15 connector.
If you do not follow this step, the unit will still use power (mainly the touch screen as it will constantly be in sleep mode).

Note that your battery will discharge at a rate of 0.5 to 1% per day.
This is why it’s recommended to fully recharge it after 2-3 months.
6.2. OUTDOOR STORAGE
Following these steps for storage will help keep your batteries safe & operational. It’s also important to recharge your batteries when taking your units out of storage, as they will be lower than 12.6 volts after being stored for many months.
We hope you have found these tips useful.
