Solar Battery REX Series Installation  and Operation

  • Recommended float charge voltage  2.27V per cell at 25oC
     compensation in function of temperature -3mV/oC/cell

  • Cycle and equalize charge  voltage: 2.35V per cell at 25oC
     compensation in function of temperature -5mV/oC/cell

  • CC-CV charge current  unlimited, otherwise 150A  max. if T>25oC

  • Preferred operating  temperature range 15oC to 25oC(68oF to 77oF)

  • Maximum operating  temperature range -40oC to 50oC(-40oF to 122oF)

  • A separate battery room is  not necessary

  • Reduced maintenance no water  addition required.

  • Design float life: 20 years at 25oC (77oF)

Solar Battery REX Series Construction

  • Positive plate --- Reinforced grids in a corrosion-resistant pure  lead, high tin, low calcium alloy

  • Negative plate --- Lead-calcium alloy grid

  • Separator ---  High  density microporous glass mat with low electrical resistance

  • Container & lid --- High strength ABS(HB). Optional flame retardant F V-0 and halogen-free versions available

  • Electrolyte --- Sulphuric acid with a density of 1.28g/ml  absorbed in AGM

  • Terminal design --- Patented leak resistant seal configuration with  brass insert

  • Safety valve --- Calibrated opening pressure , the valve  equipped with flame arrestors for  increased operational safety and service life.


How long a battery can last?

The service design life of a battery are vary considerably with how it is used, how it is maintained and charged, temperature, and other factors.

Do batteries self-discharge when not in use?

All batteries, regardless of their chemistry, self-discharge. The rate of self-discharge depends both on the type of battery and the storage temperature the batteries are exposed to. However, for a good estimate, Narada batteries self-discharge approximately 4% per week at 80ĄăF.

What is battery cycle life?

One cycle of a battery is a discharge from full charge to full discharge and a return to full charge again. The total number of cycles a battery can perform before failure is called its Cycle Life. Moat battery manufacturers will not discus the Cycle Life of their product. Many advertised Deep Cycle batteries have not been tested, or, which is the case with cranking batteries, were never designed for long Cycle Life .
