Shelly 2.5 gets pretty warm with 600W constant load

Shelly 2.5 gets pretty warm with 700W constant load, 350W each channel.

Does the heat come from the measuring shunt or from the "always on" relay?

Should i bridge the relay since i do not really need it?

I use it for monitoring the two solar micro-grid-tie inverter.

Yep, at more than double the price.

A 300W solar grid tie inverter costs $50

The split-core EM costs $35 per inverter, the 2.5 only $13

Guess i will slaughter the 2.5, remove the relay's and solder in bridges.

Alternatively we could convince the developers to pwm the relais. After full power to activate reduce power to 1/3 to keep them activated. I hope they have a flyback diode over the coil already? Just a firmware change, the esp8266 can do pwm nicely.
