   QThe product has been connected to solar panel, but why is the PV Charge indicator still off?

AEnsure the solar panel has been correctly and tightly connected to the MC4 terminal. The indicator would be off when the working condition is not satisfied or in the dark.


QWhy there is no AC/DC output?

ACheck the indicator of battery capacity. When the product is short of power, the indicator would be off. Please charge the product timely to avoid damaging the battery, which would shorten the service time of our product.


QWhy is the indicator still on when turning off the product?

AIt is normal. There is a slow discharging period lasting about 5 seconds of the inner electronic components when turning off the product.


QIs it available to use the same appliance but the discharging time turns to be different?

AIt’s normal because time of discharging is effected by the outside temperature, using time or other factors.


QUsing the same solar panel for charging but why does the charging time vary from the technical parameter?

AThe charging time listed in the technical parameter is calculated in the condition of 4.5h of sunshine heating with optimal environment. And the real charging time is determined by the natural conditions like daily sunlight hours, sun light intensity and temperature, which would be varied.


QWhat’s the reason for unable to use appliances within the system rated power range?

AProduct model ends with F outputs modified sine wave which restricts the application of devices like electricity-saving lamp, which is normal. It could also happen to high-power appliances like refrigerator and electric drill effected by output waveform resulting failure of use. Suggestion for using such kind of appliances would be keeping the starting power less than the instantaneous maximum power of the product. For more information, please consult our engineers.


QWhat’s explanation of that when the electric capacity showed as low when applying high power appliances, while using low power appliances it turned to be more electric capacity?

A The indicator shows the current remaining power under the load power. As in the same condition, the servicing time for high power appliances would be less than the low power ones.


QWhy does the capacity turn to be low while it went back by switching off?

AIt is a dynamic changing during working period and the indicator shows the current remaining capacity during working conditions. When switch off, it turns to be standby showing the actual available capacity.


QWhy does it turn to be gradual during charging showed by the indicator when charging by battery?

AIt varies by different batteries that used, which results in various charging time due to different parameters.


QIs it possible to charge the battery when the indicator shows to be out of power?

AThe battery needs to be charged when the indicator turns red and keep the product fully charged for long time storing.


QIs there any solution for emergency charging while the capacity of battery is used off?

AUse 12V battery to connect the 12V DC terminals kit by A type or B type connecting wire. After connection, switch on AC switch instead of Power Switch (MS) for power supply.


QCan it be used as solar charger to charge other 12V battery?

AConnect 12V battery to the 12V DC terminals kit by A type or B type connecting wire then connect with the solar panel. It comes to services as charger instead of turning on the Power Switch (MS).
