Will watt meter work in-line between a 12 volt dc 75 amp 900 watt power supply and 2 battery chargers that each operate at 12 volt dc 10 amps 200 watt

Yes this application should be fine just remember to limit the current through each meter to no more than 40 to 50 amps. I use one of these between my power supply and my name brand power strip with power pole connectors for my amateur radio staion and whatever else I work on. D Coffey

As long as you wire your 3 12volt batteries in parallel, this panel will work. There are built in bypass diodes. But to avoid back flow charging from the battery, you will need either a charge controller and 5Amp is sufficient for the rated current of charge controller.

Haven't tested this one specifically but almost all that have been legitimately tested that are similar to this one have 2.4 total so if you have one item plugged in it will draw up to 2.4 a. If you have two plugged in the unit will allocate the 2.4 amps between both items but no more. There are plenty of chargers out there that will deliver a full 2.4 amps to each usb port but they are a little more expensive.I hope this helps and good luck!Chris

You have to calculate the total needed power for your appliances. This converter has 100 Watt capacity. Add the watts (power consumption) of each device you going to connect at the same time. They should not exceed the 100 watt.Volt x Ampere = Watt

Cannot say for certain, but volts are volts, and watts are watts. It should work just fine.

If you go to 1000 watt you can charge a 12v battery bank then 2000 watt for 24v battery bank with this charge controller

This one will likely not work at all. I would suggest you get a voltage transformer rated at 900W or more.

500mA at 5V, not 2100mA as indicated -> You will have to calculate Watt from that, but is very low and slow compared to all the other chargers on the market!

yes but remember you voltage is close to max, my max with PV is 19.2, the meter works great. DS

Yes if you have solar panels that put out as much as 32 amps controller. 12v x 32a =390 watt. This is a pretty big system.

Yes it will. I have actually tested this power supply with a load that draws 20 A forabout 1/2 hour and it did the job without problem. The power supply is rated for 30 A,but I never tested it at 30 A.

Yes. The ports correspond to wattage output. Using the wrong port would cause a higher watt device to charge slowly or a lower watt device to overheat.

it will work only if the 12 volt dc power supply outputs a 12 volts at 5 amps minimum

This Power Supply can be used as a meter but is not very accurate and is not advised because it has a limit of 30 volts. The display shows amps and volts together.

Thanks...i used a small 5v USB charger and powered it from my switched AC source. I just don't see where anyone mentions you need an independent supply of 4 to 30 V to run the meter. I was planning to use the power supply I was building into a case with the meter to show voltage and current being used by the connected devices.

The 12 volt inverter takes 12 volts DC and outputs 110 volts AC. If your stuff requires 24 volts AC then the inverter will not work. However, most chargers for electronic devices work using 110 AC even though they output 24 volts DC.

I'm sure that is max for the unit. Using two 1200W devices isn't the problem, the issue would be how many amps they'll draw when in use. For example, if you connected two 1200W grills, it'll not work due to the amps.
