  1. Kool Energy / Mecer 1 / 2kW not charging to 100%

    The manual says it needs 35V min. MPPT Voltage Range 35V~100VDC

  2. 2 X 12.8V Revov 120/200ah Batteries in Series + Mecer 2400 Inverter

    Alphajohn replied to XL1000's topic in Batteries
    Picked up problems with Mecer Lobo (1440) and 20A. On small loads the V reading of Lithium too high to register as needing to charge so it switch strait back to float with no fan running, yet draw same current as the charge setting. This cause heat that can damage the inverter. The excess heat seems to be small enough with 10A and no fan for the inverter to cope. So would stay away from 20A.
