From Evnvoy FW7, Just can login into Enovy using Bearer Token,
I have made a simple code using VB.NET to
(1) Retrieve a Token from Enphase Token Website
(2) Using the Token, access Enovy's Data
Note. Need to add a certification validating code for Envoy, because envoy's certification is not valid.
Note. Ihave added json.vb for JSON file decord and using in the code
Recently, I have bought Tesla Model 3, and I have decided to expand solar power for this vehicle.
and, Installed 4 used panel which have bought from eBay
270W panels, 10+ years old, and the actual power is around 240~250W.
Include the wood frame, I have spent $200. Due to the power expansion, I have upgraded my charger also,
This is a 96V charger, but support 48V battery. and allowed up to 180V input (in H/W, 250V is maximum).
I have spent around $400 total, and $280 after tax credit.
the estimated energy per year is 900~1000kWh per year, it is $170~$185 value. and I can return my investment atter 1.5years.
When use a home back-up power using Generator or Inverter, the peak power usage of the centeral AC is the biggest trouble maker. such as I have been using XW Pro for the whole house back-up, this inverter has 6.8kW continous power and 13.2kW peak power base on the view of Central AC. This inverter can run my 2.5t Centernal AC's Compressor but there are so high tranformer noises.
I have decided to install a soft-starter to reduce the peak power demand when start-up,
My AC's LRA is 67A (16kW), it is too high to handle by my inverter, but, practical usage is just around 40A (10kW). it is why my inverter can support barely. BUT, if there is the other temporary load, my inverter will got damaged if running without a soft-starter.
my AC is not smart enough, and it can be stalled, it means, can lost a key parts.
Micro-Air EasyStart 368 is an only solution in the market, this is the connection method
and, final
At the first run with soft-starter
Peak demand is 37A (~9kW),
From the second run, the peak demand has reduced to 18A (~ 4.5kW), not, there is a marginal power for the other loads. and, Motor/Compressor starting power has soften clearly.
