So I got the txv put in. Sorry for the bad pictures, I was working in the dark/ grow lights.
I added a service valve right before the condenser in order to get a more accurate pressure reading in order to calculate subcooling.
I filled her up with propane and the finished measurements were, 205psi Discharge/at condenser, 70 psi suction, 102F liquid line temp right before txv. 690 watts.
So 205 on R290 PT chart shows 112F, so 112F - 102F = 10F subcooling. Not bad at all. I will get more numbers and see how well she runs tonight. Gonna get down to 36F.
More soon
