I would really love to learn/understand more about this stuff in the mean time - nuc with remote access works for me lol
Remote controlling when PIP is on is not the problem, Daniel's project solar-sis includes code for gathering stats, and recentlycode for setting several parameters was merged into the project, mainly:
-output_source_priority
-charger_priority
-bulk_charging
-float_charging
-utility_max_charging
-max_charging
-back_to_grid
-back_to_battery
Using
solar-sislatest set commands for the PIP, you can have whatever kind of controlling you wish, me for example in domoticz:
What I'm trying to anchieve is to turn the inverter completely OFF and then be able to turn it back ON, like if you would switch it physically.
This is because I'm using 2 inverters for different loads on the house, and PIP is necessary only when bigger loads are needed (Boiler, washing machine, dishwasher), the rest of the time should be OFF so to not waste energy.
Here's what coulomb from
AEVA Forumswrote answering my question:
The AC start switch carries battery voltage, so you need to be careful with fault currents. A ~1?A 60+VDC fuse would be wise, on the pin 1 side. The switching current is quite low, however. Hence, many small relays would be suitable, perhaps even a printed circuit mounting type, but to be safe its contacts should be rated at 60?VDC. Any current rating would be suitable. Many cheap relays' contacts are rated for 240?VAC, which sounds plenty, but their DC rating might be as low as 28?V, making them unsuitable. Merely wire the normally open contacts across the start switch. The start switch needs to be off for the raspberry to control the PIP, obviously.
So I will try to use this:

Hope it works.
