I'm hoping someone can help me out with some possible solutions here.
Context:
I use my NGC-5 as my astronomy computer. Via the appropriate software, it controls my telescope, astronomy camera and planning software. I power my entire set up with a homemade power box that has both a 110v AC input and a 100 amp hour LiFePo 12v DC battery. On the 110v AC side, I have an AC to DC converter that then provides 12.8v of power. The 110v AC to 12.8v DC is the default leg for power with the LiFePo battery leg when there is no 110v power or it acts as back up should I lose 110v power. I have everything running thru 8 different fused circuits along. All wiring and connections use 14awg wire and Andersen PowerPoles. To run the NGC-5, I use a dedicated circuit (its the only item on that circuit) and I use the factory power adapter (19v at 4.74 or 90 watts) plugged into 300w pure sine wave inverter on that curcuit. I also have a 3rd party power adapter that will bypass the need for the invertor and provide 19.5v of power up to 4.62amps or 90 watts.
Problem:
When running off the battery the NGC-5 will often cause a fault in the 300w inverter resulting in a shut down of the NGC-5. The same thing happens (often) when using the 3rd party power adapter but instead the NGC-5 just loses power for a brief instant. This never happens when running off the 110v AC to 12.8v DC side.
I've measured the amp draw just before these loss of power events. The amp draw surges above 10 amps and I've seen numbers of over 16 amps before - again these are very brief. However, at 16amps at 19.5v, that's 312 watts and causes the invertor to trip. Additionally, both power adaptors are only rated for 90 watts.
Question:
Why would the NGC-5 need to pull that much power, even for brief moments? Is there any way to throttle the NGC-5 to never exceed a certain power draw? I looked in the BIOS and there was nothing that immediately jumped out at me.
Any help you could provide would be most appreciated!
