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.
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.
Please refer to the images below to see which one you have and how to proceed with your model.
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.
Figure 19 - Measuring voltage with a voltmeter on a
first-generation solar regulator
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.

5. Auxiliary outlet charging
|
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.

Figure 21 - IQ4 smart charger |
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.

Figure 24 - Recharging times for 6V batteries |
Please refer to this state of charge graph to ensure proper unit voltage when unplugging the charger.

Batteries perform best in the first three years. If well maintained, they can last up to five years.

6. Storage
|
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.
1. If you are removing the batteries from the unit for winter storage, charge them to 12.6 volts and store them in your shop/garage (warmer area).
2. If you are
not removing the batteries from your unit for the winter, please do the following with your solar regulator:
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
- Charge unit to 12.6 volts.
- Make sure the solar regulator is connected and deploy the sign in your yard (prevents batteries from remaining idle and freezing).
- Deploy solar panels at a 45- or 60-degree angle, depending on your equipment, facing South if you are in the Northern hemisphere (if possible).
- It is important to maximize solar panel usage during winter as there is less sun.
- Clear solar panels of snow or anything obstructing them. Batteries will drain if solar panels are not cleared.
- 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.
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.
