    Batrium Watchmon4 in Node Red

    I also had a few SD cards died while using grafpi soft from Daniel. So I decided to use a SSD instead with backups to an HDD, and so far so good.

    the "this sounds like a fun project" powerwall (in Belgium)

    Thanks Wim, I'm using a ABB S5N 300A for a year now, and the shunt trip it's connected to the middle of my 14s battery (7s should fit the voltage spec of the shunt trip), and relay'ed by the watchmon. Since this is NO and only uses power when triggered, very briefly I consider this to be ok...

    the "this sounds like a fun project" powerwall (in Belgium)

    Hi, how did it go with the DC breaker, does it have a shunt trip, does it work ok with batrium watchmon? Please share your experience with it, since a friend is considering it for his powerwall. Thanks

    Esperyd?s Raspberry PI project

    Beware that when setting between SBU and other source priority the PIP as a 10min buffer interval before it will switch back to SBU. I also have the PIP5048 and I added the PIP commands for these settings in solar-sis, and they should work quite nicely. Using PIP reported voltage*current for...

    Esperyd?s Raspberry PI project

    for example solar from PCM (using solar-sis logging into influx) select sum("wh") from (select watt/60 as wh from(SELECT MEAN(charging_power) as watt FROM "autogen"."pcm_query_general_status" WHERE time > now() - 16h GROUP BY time(60s) fill(null))) this gives me Today solar production in...

    PCM60X setup and MPPTracker software

    what's wrong with solar-sis from Daniel? It logs to influx which can be viewed on grafana and optionally to emoncms also. I use it on a daily-basis and it's great.

    DC-DC charging

    From what I understand the mpt7210a is a BOOST converter, which means that the scooter battery would have to be always higher than the powerwall....which might not be the case. Also 10a is only ~500watt, I was hoping to charge at least ~1000w, 20a. How does an MPPT does current limiting?

    DC-DC charging

    This might be a problem, I don't really understand how current limiting is done.... But what about the situation where you have a huge amount of solar panels capable of delivering much more amperage than the solar charger controller limit is, would that also blow the FET inside, or is the...

    DC-DC charging

    The PCM60X is also not a lithium charger, but it does charge quite nicelly lithium if you set the bulk and float voltages to same value. So I assume a standard PWM charger should be able to do a similar job of charging a lithium battery if you can set its bulk/float voltage values. So maybe...

    DC-DC charging

    How can I charge the battery in my scooter (14s30p) Li-ion from my Powerwall (14s80p) directly (meaning DC-DC and not DC-AC-DC)?? What kind of charger / controller is necessary to be able to transfer energy from a dc source which may have between 42-58v to a dc destination to fill up such 14s...

    No, just dummy hardware (virtual switch).

    like I wrote above (check what port you have configured, mine is 3001, adjust accordingly): curl http://localhost:3001/output_source_priority?source=00 curl http://localhost:3001/utility_max_charging?current=10

    Controlling PIP-4048MS Remotely

    Peter, from my observations if you have AC IN connected to the PIP it will still draw some power (~20 watts like you wrote) from the battery because the inverter will not completely shut off. BUT, if you cut AC power to the AC IN connection it WILL shut off completely and do not draw ANY watts...

    Esperyd?s Raspberry PI project

    Since my last contribution to solar-sis there are a few commands already defined in the files for the PIP and PCM60x setting of several usefull parameters, and you can use them in console for example: curl http://localhost:3001/output_source_priority?source=00 curl...

    Portuguese Powerwall in Poland

    just a bit of an update: I spent a week vacation on Cyprus, leaving the powerwall working and during this time I was monitoring its status remotely, and noticed that everyday one of the packs was getting lower and lower top voltage, until 1 day before my return it was difference between 4.1 and...
