    • If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters an eye, flood the eye with running cool water at once for at least 15 minutes and get medical attention immediately following. • Baking soda neutralizes lead acid battery electrolyte. Keep a supply on hand in the area of the batteries. •...
  • Page 8 figure 2.3 The graphs above represent the max power output for a given input for each Classic. Using and understanding these power graphs will help maximizing Classic’s output power and aid in selecting wire and breaker/disconnects. The built in set up wizard also helps select breakers and wire sizes. Notice that lower battery voltages and lower PV input voltages result in higher continuous output power.

    #4 AWG. 4AWG THHN wire when installed in the Classic and MidNite E-Panel is rated for over 100 amps and is therefore suitable for the highest power Classic 150. Over Current Protection and Wire size requirements The over current devices, wiring, and installation methods used must conform to all electrical codes applicable to the location of installation.

  • Page 22: Current Limit

    1.56 times short circuit current for PV over current protection. This is reduced to 1.25 times when using a breaker rated for continuous duty. All MidNite Solar breakers are hydraulic/magnetic and are rated for continuous duty. No de-rating is required for the output breaker when using MidNite Solar breakers.

  • Page 32 Absorb: This stage means that the Classic will maintain the absorb set point voltage until the batteries are charged or it reach Float stage. At this stage the classic is not putting out maximum current as that would increase the battery voltage over the Absorb set point. This is also referred to as constant voltage mode. The absorb time is proportional to the bulk time.
