Detailed Product Description

Description:

This solution is designed for remote area without AC mains power. It uses solar + generator power supply, and uses batteries as energy storage component.

Item	Technical Parameter
Load	1100W, DC 48V ( provided by the customer)
Equipment Compartment Cooling	1500W, AC220V air conditioner
Battery Compartment Cooling	500W, AC220V air conditioner
Generator Power Supply	80hours
Battery backup power supply	18hours
Ingress Protection	Equipment compartment, battery compartment: IP55 Generator compartment: IP45

Note:
1.The batteries charge and discharge frequency is high, so we recommend to use Iron Lithium Battery. The advantages of Iron Lithium Batteries are: anti - high temperature (up to 55°C), high battery cycle times, deep discharge, large current charge.
2.About the air conditioner, we recommend to use AC air conditioner, which is with high cost performance ratio.

Working Principle:

1. In case of the solar cell panel working normally:

(1) During the daytime, the solar power provide power supply for load and battery charge; In the nighttime, the batteries discharge and supply power for the load.

(2) We assume the standard sunshine intensity is 6 hours in the area, the batteries working time is 24 - 6 = 18 hours.

2. In case of cloudy and rainy days, without sunlight:

(1) The batteries discharge; when the batteries voltage is lower than 44V, the UPS will send switch signals and start the generator, then the generator will start to provide power supply for batteries and load.

(2) When the batteries voltage is restored to 53.5V, the generator will be turned off.
