Battery power/requirements ?

You have the clamp meter over the PE?

The battery monitor is showing the net current. What about other loads and any charging like Solar?

It's in the garage so no solar, everything else switched off. The control panel usually uses 200ma ish so that will be included in the battery monitor reading.

Well, you have a remarkable setup there with a 24" LED TV that uses the same power as a little strip of LED lights depite the voltage conversions it has to go though and illuminating literally thousand of LEDs in use, and an inverter that in use uses less power than most inverters in standby mode.

Just checked again, this time the mains power consumption on the little watt meter I fitted.

New LED tv's are a lot more efficient than those of even just 10 years ago. The 24" LG TV we've got now is a 2021 model. The one before was a 2011 Samsung 18" LED (still LED back-lit) and used about the same power.

My 24 inch Toshiba TV is 2 months old but states it uses 45 watts.

Says 19v 2.0A on the back of ours. That will be absolute maximum.(38w)

I've had evil thoughts of trying it on 12v but don't want to break it. It will probably have voltage switch mode regulatory feedback thingys in it so might work

My TV has a power saving picture mode which I assume saves a few watts but as it only takes about 4amps an hour anyway, and I will have about 100amps (max) usable I'll just leave it set on dynamic picture.

What inverter are you using? Looks like half the power is being used by that.
Our small 200va Studer inverter only uses 2.4w or 0.2a @12v

The inverter I have bought is a Streetwise modified sine wave, 500 watt continuous/1000 watt peak.
