Not sure what you are asking. The Amp hours of the power station will depend on the batteries you are using.

I’m not quite sure I understand the question. Basically with 4 x 7.5 AH battery the power station can supply about 1700w for one hour. This is in an ideal world. If you lower the load the batteries will last longer. Hope this helps.

Most of my equipment has an amp rating not a watt rating and I was looking for a way to judge the capabilities of the Nexus in AH's. I use 4 x 7.5AH batteries.

A * Volts = Watts
AH * Volts = Watt / Hours
7.5 AH * 56 V = 420 Watt Hours
AH * Volts = Watt / Hours
7.5 AH * 56 V = 420 Watt Hours

Maybe it would be better if you could give an example of what equipment you would like to run on the Nexus. Also specify the amp rating and maybe I could try to calculate it as an example for you to use.

watts = volts times amps
similarly watthours is volts times amphours
the ego batteries are 56V and have their amphour rating on the side (for example 7.5 Ah, 5.0 Ah, 2.5 Ah)
so one 7.5 Ah Ego battery is equivalent to ...
56 Volts * 7.5 Amphours = 420 Watthours
My configuration is 2 7.5Ah batteries plus two extra batteries from a mower (4 Ah) and a string trimmer (2 Ah). So the total watthour capacity of my system is ...
56 Volts * (7.5 + 7.5 + 4 + 2)Ah =
56 Volts * 21 Amphours =
1176 Watthours
You can work from the AC side too. If you have a device that draws 5 Amps on a 120V circuit, that's 120V * 5A = 600 watts. for two hours of continuous use that would consume 2h * 600W or 1200Watthours of electricity. My almost 1200Wh setup would be almost enough to run that load for 2 hours (maybe 1h45 with losses due to the conversion of 56V DC to 120V AC)
