  1. Question about getting SOC from x Deye 8kW in 3 phase to switch on geysers on CBi Astute

    TiredTractor posted a topic in Home Automation
    I currently have Wifi loggers on the com ports. I have my geyser on a CBi Astute (Tuya) switch and I want to switch on the geyer when the battery SOC reaches 95%. For what it's worth the batteries are 16 x Pylontech US3000C. Inverters SUN-8K-SG01LP1-EU From what I can gather I would need a Raspberry Pi with Solar Assistant connected to the system with a RS485 cable and then another Raspberry Pi running Home Assistant. Given that I just want the SOC, would a single RS485 cable be sufficient?

  2. 3x 8kW Deye hybrid's connected in 3-phase parallel

    TiredTractor posted a topic in Inverters
    Good day, I have the 3x Deye 8kW inverters set up to run in parallel to produce 3-phase. Batteries are 12x Pylontech ~3.5 kW lithium (US 3000C PylonTech) My question is regarding the Maximum Amps for Charging (from DC / Solar). The upper limit is 185A. My question is this, given that there are 3 inverters that are running in parallel in 3-phase, does this mean that the total Amps of the 3 together is limited to 185A or would it be a case of the 3 together will never exceed 185A? I have batteries in parallel and connected to the system with a single 200A Solar Disconnect box / fuses. Not sure it this is sufficient or if it should be able to cater for the total Amps from the 3 invertets. Eg. have a 400A fuse and set each inverter charge only at 133A? or is 200A sufficient as the totat will never be more than the 185Amps. Thanks
