>2000 times, Left 80% Power capacity

Real outdoor to test UPS of C-LiFePO4 Lithium Batteries after 1200 times are still have 95% power capacity

3

Service life
(for Indoor Used)

1~1.5 years

1.5~2.5 years

>7 years

Solar DC UPS of C-LiFePO4 Lithium Batteries for indoor used, will have more battery cycle life

Proportional to the design capacity plus

More than 180%

(Deep cycle battery required bonus 150%)

More than 150%

More than 110%

For the sake of the system enough power capacity of the equipment operation, designs are subject to decay to add on, to cope with the operation of the system power supply enough

8

Match Solar Panel

Design wattage required bonus 180%

Design wattage required bonus 150%

Design wattage required bonus 110%

Having regard to the increase in battery capacity to match more of the solar panel, so will affect the set up costs and space used for erection and erection equipment difficulties, for the system is satisfied that requirements for the assessment of projects.

9

Set up space and erection harder

Solar panel need more wattage and size

Solar panel need more wattage and size

Solar panel wattage can match the design and area

Solar panel is too large, would create a wind pressure of an area to improve many, resulting in erection and maintenance of security risks increase, too heavy batteries, too

No

No

C-LiFePO4 Lithium Batteries can fast charging and large current discharge

11

Security

Releasing toxic gas and explosion hazards

Have explosion hazards risk in 50~60°C

No explosion risk**

Solar DC UPS of C-LiFePO4 Lithium Batteries @short circuit conditions, maximum temperature up to 120~130°C, at the same time have the security design of the pressure relief valve, so no explosion risk (please see the test report)

12

Maintenance costs
