    Heat Pump water Heaters

    I have a rheem heat pump water heater for a year now. There are 2 of us in the house. I have a bunch of solar panels up 7kw worth. Our normal use is between 700 watt hours and 2.5 kilowatt hours for the power reported from the device as it is on wifi. It has a high demand mode for fast...

    Tinkering on a DIY Solar Generator/ Questions if I'm on the right track for power expectations.

    Oh this reminds me of how i started. Same kit from harbor freight (a designer drug). I then went on to add some 100 watt panels and an eperver charge contoller. I now have 4 growatt all in one hybrid off grid inverters doing the whole house (AC and dryer). Batteries are tricky on the percent...

    Growatt split phase

    The neutrals need to combined and run to the same load center as the hots. I have 4 growatts 3k in a split phase setup and works great. The host one needs to on first. No power sharing cable (green twisted cable) for only 2 growatts. The growatts need to be connected to the battery though...

    Off-grid solar and ham radio noise

    One option to try is to put 2 caps (high voltage) in series with the middle going to ground. One these on the PV coming and the other on the battery cable. I have had some success with this but perfect It is cheap to try. A fellow ham here

    I Can't Afford So-Called "Tier 1" Equipment. What's Good at Tier 2?

    I have been doing it the same way at my power corner. Plywood with tile underlayment on top. Works great for moving things around. My evolved over time as i learned more and "needed" more. The rules for grid tied in calif changed and wanted to be prepared for it.

    I Can't Afford So-Called "Tier 1" Equipment. What's Good at Tier 2?

    I have 24 volt versions on the wall and they are working great. Solar assistant does a great job of adding the missing pieces that is not in the cloud or on them. I am now running a 3 ton AC off grid with the rest of the house.

    Biting the bullet. Doubling my battery capacity $$$$$$

    Correction This IS addictive. I started with a smal harbor freight and now have 4 diy batteries, 4 growatts, 4 load centers and the whole house connected to it. Pacific Graft and Extortion does not get any of my money. The hybrid electric water heater does a great job of lowering the gas...

    Does Solar Pay for Itself? Is it worth it?

    Check in a product called Flume. It is a meter reader realtime and does alerts via email text, and connects to home assistant. It works great. It is about 150 bucks.

    Looking for a battery or PV monitoring app with a production graph over time.

    I am using Solar Assistant. It is a raspberry pi setup that logs everything connected via usb I have mine connected to 4 batteries DIY JBD and 4 growatts. It then uses MQTT to talk to home assistant.
