3.Product feature and application of portable solar power kit 

DC output system with multiple interfaces can satisfy various demands. DC output interfaces are including 1pc 12VDC/3A and 1pc 5V, 2.1A.

Standby function under lower power consumption: after the startup in three minutes, if no detection on the output load, the system will automatically switch into lower power consumption standby mode.

Charge and discharge independently: discharging could happen when charging; both of them are not interfered.

Charging display function: solar power light shall lit when solar panel start to charge for battery.

7.Can a stand alone system be installed by a qualified electrician, who is not a contractor? Here a contractors license is required io connect to the grid?

A basic stand alone system can be as simple as a single PV panel, battery and charge controller which can be connected or installed by the home owner. Different regulations apply to different countries.

8.Can the pool pump be directly plugged in to this system?

Changing a mains powered AC pool pump for a high volume solar powered low voltage DC pump driven by solar panels during the day is a good way to use solar energy. Depending on the volume of water you wish to circulate, either in gallons or litres per minute will determine the size and voltage of the pump and thus the power output required by the solar panels.

What are off-grid solar systems?

Off-grid solar systems, also known as stand-alone solar systems, provide grid like electricity in areas where grid power is either unavailable or directly replacing expensive or unreliable grid power. Off-grid solar systems consist of roof- or ground-mounted solar panels, a battery bank to store energy, an integrated backup diesel generator and an Inverter and/or Charger to act as an interface between the different inputs.

The system size is infinitely variable, Carspa has designed set ups that supply energy to run a fridge and TV, to supplying a complete island or remote community with electricity. Carspa also designs leading-edge off-grid Solar Irrigation Systems for pumping water.

In larger systems there is often a diesel generator integrated to assist in periods of higher than usual demand or to act as a backup for extended periods of bad weather. Other renewable sources like wind and hydro can also be integrated if the environment allows for this.

Compared to older off-grid systems, modern off-grid technology is very easy to maintain, fully automated and can be monitored and controlled online. A further benefit of modern off-grid systems is the quality of the power they produce. This power quality is often better than the average grid electricity and will extend the lifespan of your appliances and machinery.
