Help with 1500w Inverter. No power output.

Struggling with this and I'm at my wit's end.
Here's the system.
In my van.
1500w schumaker inverter
50ah lipo battery
100w solar panel 
10amp mppt solar controller

System works beautiful but inverter is no longer functioning properly. When I turn it on the power light (on the inverter) turns on indicating all is good. But there in no power outputting (the USB ports work fine) from the inverter. If I leave a light plugged into inverter while it's turned on it will occasionally flicker.

I've checked on the cables. 
Battery is good. 
I opened the inverter and checked fuses and looked for something burnt but didn't see anything.


Anyone have any ideas? 
What's my move.

    Welcome to the forum  @gershee

    The occasional flicker may be the inverter has a search mode and the light is too small of a load to prompt it to power up. Try a larger load, preferably a resistive one or disable the search mode if applicable.

    The battery and PV capacity is too small with relationship to the inverter, this could lead to the BMS cutting the load due to low voltage, however as no information is provided this is merely speculation.

    So everything worked perfectly the last 3 years the inverter not working properly is a new thing. 
    I've tried with different loads including my blender which seems like a larger amp draw. 
    Still nothing.
    Anymore ideas or steps I can take? 
    Thanks!

    Have you had any lightning around the time of the inverter failed to operate? In the past I lost one due to a near strike as soon as the strike hit~25 meters away the inverter shut down, the power light was still on but no AC output, I saw the strike so I know it was the cause.

    Negative no noticeable lightning. 
    I guess I posted because I'd love to be able to fix or even attempt to fix the inverter but more than opening and checking fuses and looking for something burnt I have no clue what else to do..
    Trash it and get another?
