This article explains the various errors/faults that can occur on your Cloud Solar device and the basic steps for troubleshooting before the device is declared as broken. 

The Charge Controller does not turn ON

• It could be due to incorrect or loose connections. Ensure that the connections are correct as in the below image and are connected in the order shown below. This is shown in more detail in the installation guide that comes with the Cloud Solar device and is found in the Installation-Guide
  

NOTE: Connect the battery to the battery port. As the charge controller cannot protect the wire between the battery and charge controller, an additional fuse should be installed close to the positive of the battery terminal.

• It could be due to incorrect specification of the Battery /  PV panel.

1. Ensure that the battery is either 12V or 24V.
2. Ensure that the PV panel does provide more than 55V open-circuit voltage and 20A short circuit current as it can damage the components on the device. You will find this printed at the back of the panel as Voc and Isc.
3. If you have found that an incorrect battery or panel was connected to the charge controller and if the controller is not turning ON, please contact support@cloud-solar.com with the details.

The network LED is OFF

1. The Cloud Solar device comes with an Aeris global sim card by default unless you have preferred to use a local sim card and have asked to ship without a sim card.
2. After turning on the device, check the Installation-Guide to know whether the device is trying to establish a network connection or not from the LED pattern mentioned in the guide.
3. If there is no response from the network LED, it can be assumed that Aeris gets no / weak signal in that location and it is advised to replace the sim card with a local sim card that has good coverage in that area.
4. If it doesn’t turn ON after replacing the SIM, please contact a Inclusive Energy member of staff with the details.

Load does not turn on

• Short circuit. If the load LED is flashing rapidly, the device has detected a short circuit.

Find and fix the short circuit. When you are sure there is no short circuit, restart the charge controller by disconnecting and reconnecting all the terminals.

• The battery has a low state of charge.

Re-charge the battery. If this does not happen after ~3 days, Contact support@cloud-solar.com, the battery or solar panel may be damaged.

• The load has been purposefully disconnected by the operator

Contact the operator to find out the reason for being disconnected.

Faults / Errors that will put off your load

• Disabled

The load output has been disabled automatically because the user has run out of credit or because it has been manually disabled from the dashboard by a technician due to non-payment or any other reason. Check the user’s payment info on the dashboard and if there is no payment overdue then contact the technician assigned to that user to know the reason for the disconnection. If no one has disabled the load, contact support@cloud-solar.com.

• Disabled (low battery)

In the case of a lead-acid battery, it means that the battery has discharged below 11.7V which is the load cut-off point at which load is disconnected and is connected back when the battery voltage rises to 12.3V. It is advised to keep all the load off during this time. With a bright sky, it might take 2 to 3 hours but it can be delayed depending upon the weather conditions. If it doesn't recover within 72 hours, check the condition of the solar panel and contact support@cloud-solar.com as the battery or solar panel may be damaged.

• Disabled (over current)

It means the total load (lights, fans, any other D.C appliances) that are connected to the system has exceeded the prescribed limit of 20A. The device senses high temperature and cuts off the load. You will have to turn off some load and wait for the load to be reconnected. This can take ~5 minutes by which time the load needs to be normalized.

• Disabled (short circuit)

It means that one of the loads is faulty or there is a short circuit in the connections somewhere which causes a sudden surge current and the load has been cut off. The short circuit or the faulty appliance needs to be found and fixed by a technician and then the charge controller should be restarted by disconnecting and connecting all the terminals as explained at the beginning of this page.

• Disabled (over-voltage)

This can happen when the battery voltage is going above 14.4V in the case of lead-acid batteries. It is a rare scenario but if it happens, it could be due to faulty hardware and you can contact support@cloud-solar.com. 

• Disabled (temperature)

This is seen when the PCB temperature rises significantly. It could be due to an intermittent short circuit by insects, high power consumption by the PCB or because the ambient temperature is too high. It should resolve on its own once the condition is normal. Contact support@cloud-solar.com if it is not resolved within 24 hours.

• Disabled (multiple errors)

This is a very rare scenario that the load gets disabled due to various errors deducted by the hardware. The cause could be any combination of the above-mentioned errors.

• Disabled (voltage dip)

This is seen when there is a sudden surge in current deducted due to connection of high load or inductive loads like high-speed fans/motors etc. It is similar to a short circuit which causes a sudden sag in voltage across the battery terminals. Check if any inappropriate load was plugged in and remove them. If the error still persists, contact support@cloud-solar.com.
