Off grid solar sytem also called stand alone solar system. It does not connect with Grid or called Utility. It is very popular and suitable for remote area where there is no Pubilc power or Public power is instable.
Why choose Off grid solar system?
1. Safe & Reliable
Professional Design
Support utility grid and generator voltage input
2. Flexible
12V/2V Lead-acid Battery Optional
Lithium Battery Optional
PWM/MPPT Controller Optional
Poly/Mono Solar Module Optional

Q one.Do you have MOQ?
Depands on different ideas, Can be negotiated.The larger the
quantity is, the competitive the unit price will be.
Q two.Should the customer pay the delivery fee,How much is it?
For the delivery fee,many samples are be requested to be sent,so we
must get delivery fee.
If you tell me to use the appointed Express,you will give me your
express account or you will pay according to the Express.
If you do not request,I will choose a cheap one in China.
Q three .How about the after sale service?
1)We will always keep the quality the same with the same and if
there is something with the quality,we will make compensaton for
our coustomers.
2)We will suggest our packing and take charge in our packing,we
will keep the goods safe in the delivery.
3)We will trace the goods from the production to selling,we will
slove the problems in the selling for our coustomers.
Q four.When can I get a price?
We usually quote within 24hours after we get your inquiry.
