15A MPPT Charge Controller FAQ
How do I know if my controller is working?
You have a single LED on the controller. This will light Green is the circuit is producing power and connected the correct way. If this light is RED then it could be one of the below reasons
No solar input from the panel (check connections)
Panel is not connected (check connections)
No sun outside (wait for the sun to come up)
Very low sun light levels (wait for a brighter day)
Battery is not connected (check connections)
Battery is below 11v DC (remove battery and recharge with a recommended charger)
How do I connect my phone?
You must first install the software from the App store corresponding to your phone.
Once it's installed, open the app and click on the connect button. This will then search for Bluetooth devices, select the device called PV- xxxxxx (the x’s will be numbers). The app will now ask for a password. This is the numbers after PV-. Once entered you will see the data coming from the controller.
Where is the app available to download?
The App is available to download from both the Apple App store and Googles Play store depending on the device you are using. Please search for “PVMobileSuite”
I have a battery bank with two batteries in do I need to connect then up to battery '1' and battery '2'?
No, the two battery outputs form the controller are for separate circuits. For example, your leisure battery circuit and your engine battery circuit
Can I charge a 24v battery from solar with this controller?
Yes this is possible, But you will need to give the controller a feed from the solar panels above 40v (i.e. a 24v solar panel or 2 x 12v solar panels connected in series) the controller will then automatically adjust the voltage to suit a 12v or 24v battery depending on what you have connected to it
What range has the Bluetooth got?
On average Bluetooth has a range of around 10m (line of sight). But this will change depending on what is between you and the controller, for example walls etc.
Can I see from home what my solar system is doing?
If your controller is within 10m then yes there is a chance you can see the data from the controller. If it's over 10m then it's out of Bluetooth range and you will not be able to see the data.
Why is MPPT better than PWM?
Most modern charge controllers use Pulse Width Modulation (PWM) that slowly lower the amount of power (current) supplied to the batteries as the batteries get closer to a fully charged status. A PWM controller allows the batteries to be fully charged with less stress on the battery, extending battery life. It can also keep batteries in a fully charged state (called “float”) for an indefinite period.
The most recent and best type of solar charge controller is called Maximum Power Point Tracking, or MPPT for short. MPPT controllers are basically able to convert any excess voltage into amperage (power) giving you up to 20% extra power from the same panel in certain conditions.
What is the maximum amount of solar I can connect?
Most charge controllers are rated in amps. So depending on the controllers amps rating you can work it from this. For example, if you connect one 15A solar panel on a 15A controller you are at its maximum rate. However, you could connect two 5A panels (10A in total) and still have another 5A to play with.
I have a gel battery. Can I set the controller to work more efficiently with this?
Yes, in the battery option in the app you can select the chemistry of the battery. Once you have selected it you need to “send” it to the controller with the 'send' button on the same screen. The controller will reboot during this process.
I have specific settings for my battery. Can I programme the controller?
Yes, on the battery options area of the app you can select custom (please make sure you have set the system voltage first) this will let you change all the charging parameters. Once complete you will need to send it to the controller using the send button.
Can I change the password?
Yes, but we don’t recommend it unless you really need to. To do this click on the settings “Cog” on the app and go to the reset password area.
What happens if I forget my password after I have changed it?
If you have forgotten a user set password, you will not be able to connect to it to see your data. Please contact the office on (+44) 1684 774000 and speak to the support team who might be able to reset your controller. This will lose any custom settings you might have saved to the controller.
How much ventilation do I need around this controller?
Your controller will get warm to the touch when its working. Please make sure you have around 150 mm of space all around the unit and have plenty of ventilation on the position you have installed it
Can I charge my leisure and engine battery from this controller?
Yes, please connect your leisure battery to the battery '1' terminals and your engine battery too battery '2' terminals. Don’t forget to also install a fuse between each battery and the controller
Can I prioritise my engine battery?
Yes, you need to connect it to battery '1' terminals
Do I need to install a fuse from the solar panel?
No. However please make sure you install fuses between the controller and any battery.
Can I install more than one controller to a battery?
Yes, but the efficiency might drop from the solar panels
