  • Input voltage alarm on inverter

    Well I finally got my system up and running but when I turn on the inverter with no load I'm getting an input voltage alarm on the inverter.I tested the voltage coming in to inverter it was 14.6 volts is this too high ?From what I've read voltage should be 13.7-14.3??I have 4-100 watt monocrystaline panels wired in 2 strings in series then back to parallel with a 2 way splitter Multimeter shows between 39- 41 volts coming from panels to CC?.If I disconnect the panel leads to the CC the inverter works fine.The CC is a 40 amp mppt renogy.The inverter is a 600 watt pure sine wave renogy .Thank you for time in advance.This is a top notch site and has been a big help to me Thanks again

    If your charge controller is set for your batteries ( Gel, flooded, AGM, Li, Deep Cycle ) and your inverter is supposed to work with solar (many cheap inverters are for automotive use) you should not have an issue.
    And the alarm goes off because your battery charging voltage is higher than your inverter warning threshold.
