Do you know following questions about mobile solar light tower?
Q1 : Should we need to charge up the battery to power up the LED light on the 1st time, and how many hours?
Re：No need, before delivery, we will test the battery and LED light, it means we will charge and discharge it. And before loading, we will put the unit under solar to charge it to the maximum power. However, it is better to deploy it in the day.
Q2 : when the tower is moved to other projects, how long will be the set up time.
Re: Usually 2minutes is enough to deploy the unit, you just need to put outriggers down, expand the solar panel and lift the mast.
Q3 : How many hours the battery able to maintain 50% power under cloudy day, rainy day, stormy weather, show day?
Re: It depends on which model of trailer will you use, for example, If we use 3*340W solar panel mobile solar trailer to run 4*100W LED light, When it is 100% power charged, the 400W LED lights could light for 27hours when it consumes all electricity, and it could work 13.5hours under the 50% power, and 8hours under 30% power, when it is in the health use way.
In somewhere, where there are continuously bad weather seasons, we suggest the mobile solar trailer to mount the battery charger o let the trailer charged by AC power in 5.3hours.
Q4 : How many hours does the Grid mobile solar power station to be changed up in full speed, or start running?
Re: Usually we use MPPT solar controller which is 95%+ efficiency, it takes 7.8hours to charge 70% power (Healthy battery discharge depth), 11hours to charge 100% full power, and 5.6hours to charge 50% power. Generally speaking, one sunny day could charge 50% power.
When batter is charged 30%+ power, the mobile solar trailer could work normally.
