The thermal pressure relief valve should be cpvc? Anyways, I installed the aosmith vortex hpts-50 and it’s great. I like the water connections on top more but the control app is a joke. I thought rheem was a joke and this is worse.

I am running open-loop with my skybox right now since I have 3 different types of BMSes but the drawback I can see if and when I switch to a more advanced inverter is the ability for the inverter to get an accurate SOC unless the inverter has a great coulomb counter or shunt. It seems like a lot...

When I say some pros build a parallel main panel and do a cut a swing on the same day, they literally put up a new panel in a nearby location, make a new roof penetrations anyways because you are usually stepping up the imc mast/conduit to 1.5” or 2” for 200A anyways so they complete all the...

If you have the space to do this, I would absolutely do this as well because if you need to put CTs for metering or cap your sell back, it’s easier to do it on wires than some of these bus bars in meter plus cabinet combos.

If you are installing in the same location, you need to plan things out and have the crew come out and disconnect, pull your meter. If you cut the tags and pull yourself, the power company will see your meter go offline and send someone out soon to check and they can be extremely mad for meter...

The one issue with the wagos is the tendency to have one of the levers catch onto another wire and lift it up half way but I always take electrical tape and wrap the levers so they don’t have a chance flip up. I feel completely safe using them, especially when stranded thhn is involved.

You are probably right. The only reason why I'm thinking about this is because this year, I'm using the heat pump mini splits so much more (all these cold nights) and in Feb, my net usage is probably ~400KwH vs 13KwH surplus compared to last year. I also got a new HPWH which is drawing on...

The main question is since I am on NEM2 and EV2A home charging rate plan, should I use my inverter and 30KhW of battery storage to load shave, self supply during PEAK times and use PV + Grid to charge battery back. This is essentially what I did during the summer months and it seems like I have...

Oh yeah, you have to dig through a lot of documentation so see what specific meter socket is approved for which power company. Did you buy the ringless one at the local home depot?

Would you just sell the BOS portion where the solar input and breakers live?

Here is my dashboard with all the battery data I would ever need to see.

Looks like it can output data to MQTT but it can't take external MQTT data to graph battery statistics.

Does SA use MQTT data? I have 3 different battery BMSes and a smarthsunt and all the data is published to MQTT and ingested into an InfluxDB for Grafana.

If there is no safety built in, I’d be afraid the system will literally kaboom! I trust esp32s and alike for automation, monitoring but not enough to try to prevent excess solar from raising the ac voltage.

I mentioned about the skybox and AC coupling on the backed up load output. I’ve watched the frequency go up and down according to the solar + load and my old sunyboy inverter worked wonderfully. I have enphase iq7+ inverters now and originally, I’m thinking to try to keep the solar connected to...

Just throwing it out there but you could send one to me to evaluate. I really appreciate the American design and supported hybrid inverters. I currently sport the outback skybox and it is limited to 5kw so it’s hard to support a whole house with heat pumps and all but I really appreciate how it...

I second this. Why are you paying a power company when clearly this is out of spec. They should fix it right away if you have a smart meter, they can pull these stats and see the issue on their end.

Instead of fused disconnect, would a fused manual transfer switch to allow you to bypass the hybrid inverter incase it needs servicing?

So you pull a #6 for 50A breaker to sub panel from your main panel and then you can tie your solar to the opposite end of the sub-panel with a 15A breaker and you should be fine.

if you get a grid interactive inverter, the same AC that feeds the sub panel can be used to send back power to the house and ultimately net metering. Of course you have to size your breakers and cables correctly but 2.5kw is not much @ 240V

Short answer is yes. This unit will not be grid interactive so you can not sell back to grid. It will use the grid as a source for charging the battery if it goes below a defined State of Charge. You will want to wire in such a way you have a critical loads panel or a transfer switch to select...

Beyond the net metering and permit issues if you choose to deal with, you should take the enphase university courses and learn how to put their system together. Not sure if your system has enphase combiner boxes and the wiring sizing to support more ac back feed to the panel. If your system was...

I remember reading about someone fixing the voltage regulator of their skybox by replacing components.

You did put a jumper wire on the terminal block if not using external RSD switch correct? It's in the documentation.

Example of my dual interlock to cut grid to inverter and back feed from inverter load out to min panel. https://diysolarforum.com/threads/successful-200a-oh-service-upgrade-and-hybrid-inverter-connection.68753/#post-872080

I wasn’t talking about the cells but the whole battery pack integration. I think we should confirm the exact bms manufacturer and model because software and cabling won’t be the same between vendors. Just taking pictures of the bms board will allow bright people on this forum to confirm its...

Are all the settings and firmware version the same between the batteries? Sounds like an auto hibernate feature which I have not heard of so far.

Can you hook up the pc bms software to read what’s going on and any faults?

Never heard of dr software. You might as well disassemble one battery and take some pictures to see if we can identify the BMS. I hate to say it but that’s what you get for going cheap AliExpress way and not known vendors.

Mine came with a wide input dc to dc converter that I had to install. I’m guessing 48-60v to 12v

I don’t trigger any smart home automations. I just collect all this data and graph it via grafana. I’m a noob at using home assistant.

YAY, glad it worked out for you!

+1 on the openevse with the latest WiFi gui firmware. I have ev solar charging if I have more than 1kw of grid export and it works very well with filtering for sudden cloud shifts, minimizing wear on contractors or relays. For totally off grid, you just need to find out that magic number that...

You have a center fed panel so I believe 120% rule does not apply. Open an account on OpenSolar and start to design your system. West facing panels are not bad. Get a drawing and approval on the components first.

Inspectors are trained to put on blinders and only inspect what they came for. I recently did a new main panel and overhead upgrade. The inspector did not want to see the now sub panel but insisted he see the water heater for bonding. Went into the garage, all servers running with backup diy...
