Commissioning Charge

I am installing a new solar system and I need to perform a commissioning charge on the new batteries (when I get them). I am wondering the best way to do that if I don't have grid power available.

    Use solar?

    Not sure what you are asking, do you not have a solar array yet? If you do, just charge from the array until fully charged then equalize and check SG.
    Home system 4000 watt (Evergreen) array standing, with 2 Midnite Classic Lites,  Midnite E-panel, Prosine 1800 and Exeltech 1100, 660 ah 24v ForkLift battery. Off grid for @16 of last 17 years. Assorted other systems, and to many panels in the closet to not do more...lol

    Or start with a generator and finish with a few panels installed temporarily? I would expect new batteries to be near fully charged on arrival, so shouldn't take much current for commissioning.
    Off-grid.  
    Main daytime system ~4kw panels into 2xMNClassic150 370ah 48v bank 2xOutback 3548 inverter 120v + 240v autotransformer
    Night system ~1kw panels into 1xMNClassic150 700ah 12v bank morningstar 300w inverter

    If you mean that you want to charge individual batteries before they are installed in a series string: That is a good idea for many types of batteries.

    Follow the manufacturer's recommendations for any break in needed because it will vary depending upon what batteries you have.

    I always have more questions than answers. That's the nature of life.
