Current and Voltage Meter - Best?

[carlyai]

I need to do some load tests for my upcoming solar project.

I wish to purchase some current and voltage meters to install in the CU on the incoming 3 phase supply.

There are many available and I would like a recommendation on what brand to buy.

As you have noted there are literally zillions of suitable devices at various prices available on Lazada.

• What do you actually want to measure? certainly V, A, W and kWh
• Do you want it to log usage over time?
• Do you want Wi-Fi/Bluetooth/RS-485 connectivity so you can link it to your PC, smart device (Alexa etc.) or Home Assistant to analyse the results?
• Do you want it DIN mount or in a separate standalone box?

I would go for one that uses current transformers rather than direct connection, easier to wire and fewer joints to fail/get warm.

 

For brands, I've had good experiences with Chint and Tomzn kit as lower-cost units, of course the big names are there too with suitably big prices.

@Crossy thanks.

I think I will go for a 3 phase CT meter, DIN mount, WiFi Bluetooth/RS-485 connectivity and logger.

I will have a look at the brands you mentioned. 🙂
