Power meter with DC battery voltage? - thundercat - 09-17-2022
Does the power meter measure battery DC voltage? If not, can you add it as a sensor to measure DC voltage?

what DC voltage range you want to test?

From 0-600v

it's very high, i think you can find a voltage meter.

What range do you currently have?

our board only work for DC 0-5v input, so you need to use a coverter circuit, but 600V ,it's too large.

Do have converter boards that you can recommend for something smaller like 0-60v or 0-100v? I'm planning on using it to measure battery voltage on a 48v DC battery on a solar system, but would also be nice to have the flexibility in range for other projects aside from solar.
The idea is if the voltage parameter is lower than 45v then trigger the on-grid relay. Once voltage reaches 48v turn off the grid relay.

you can search some DC voltage detector module, that range DC 0-250v, you can set if voltage < XXX value, then relay ON, if voltage > YYY value, then relay OFF. such as follows:

Awesome! Thank you.
