The @BYD_BatteryBox HVS 7.7kW battery for my solar system arrived today, the order took five months. Installed it myself, that took less than two hours. Still need to put the cables into a channel. All worked right away, slightly surprised 🙂
Excellent PV production from my 6.4kWp installation, almost 22kWh for the day, including the EV range to cover my commute. #solar is great
@froniussolar please consider to add the possibility to put the Ohmpilot in BOOST mode from the solarweb app, now this is only possible via triple press of the physical button. A proper IoT solution supposes full remote control from anywhere:) Thank you !
The @froniussolar Ohmpilot working hard to divert every excess PV watt to a hot water tank on an averagely overcast day (reddish color on the below chart), impressive piece of engineering.
Received a @froniussolar Ohmpilot today. It diverts the available PV excess to a hot water tank (or any resistive load), in my case 0-2400W stepless regulation. Installation was trivial. The package did not include a PT1000 temp. sensor,ordering one separately for more control
It is the 256th ( 0x100th, or the 2^8th) day of the year 🙂
Препоръчвам сесията на Роско Иванов относно #MQTT load balancing решение —> https://dev.bg/event/iot-mqtt-load-balancing-over-own-architecture/
Using Node-RED's node-red-contrib-solar-power-forecast-plus contribution to plot (light blue line) the estimated max PV generation in ideal conditions for my location/panel orientation/time of year; seems pretty accurate so far. Useful to know what theoretical maximum I have.
Installed a DC side surge protection device to my @froniussolar GEN24 #solar inverter. It comes as retrofit option, installs in under 20 min. A lightning strike nearby can induce damaging voltages in the wires from the rooftop panels 30m away, this SPD takes care of such cases
July #solar stats: 69% of our consumption is self-generated. If we had the 7.7Kw BYD battery (on order) installed, that would have been an easy 100% self sufficiency.
The grim reality of buying anything PV related in 2022, see below the response to an inquiry about a order I made couple months ago. Other sites cite April 2023 for the same product, these guys preordered Nov 2021 and “are optimistic” to deliver this September.. crazy times
Fiddling with @solcastAPI; API supposedly provides estimated PV produce based on weather forecasting for a location. Will compare against reality and potentially use to optimize home energy usage planning
Charging an #EV 100% on #solar PV surplus, feels oddly satisfying. @froniussolar
The @froniussolar WattPilot EV charger just arrived. This is the 22kW model, we have single phase installation, so max 7.4KW would be available. Can be configured to only charge using PV surplus, and supposedly works with zero feed-in. I don’t own an EV yet,will rent one to test.
A week on #solar energy, 70% of our consumption is solar-generated. Battery (BYD HVS 7.7kW) is ordered but 6-8 months to deliver, which I am told is “the new normal” Export of energy has been set to 0%, the inverter regulates production to match consumption. It is underutilized for the moment, but things will change…
Quick and dirty dashboard update to show PV generation data from the Fronius #solar inverter API on our Raspberry Pi home automation status display
The @froniussolar #wolar inverter is now powered up and working as expected 🙂 Max load test , 6kW PV generation
The final #solar panels configuration, 18 Q-CELL 355W Not powerd yet, I will do that tomorrow. Hoping no magic blue smoke is generated
My 6kW @froniussolar GEN24 Primo hybrid solar inverter and the DIY automatic switchover box are mounted and wired. Planning on going #solar this weekend 🙂
Woohoo! My @froniussolar Primo GEN24 6.0 kW hybrid solar inverter just arrived 🙂 It took two and half months after the order, so global chip shortages and high demand are affecting this industry as well. If you try to order one today, delivery times are close to a year now.. crazy times
Mounted seven #solar panels on the roof today, 11 more to go 🙂
🍀
Thank you, Turkey, for the Adana kebab..
Components for my automatic #solar grid <> island mode switchover box are (almost) here. Now toying with placement and wiring options..
Last skiing for the season? #borovets
M10x200mm hanger bolts for roof mounting my 18 #solar panels
Google removes the Android statues from its headquarters in Mountain View. Those were fun, managed to snap a picture of them a decade ago.. https://www.cnet.com/google-amp/news/google-removes-android-statues-from-its-headquarters-in-mountain-view/
Decided to go for 18 #solar panels and a 6kW inverter instead of 14 panels and a 5kW inverted because the 14 panels I originally planned produce over the recommended MPPT voltage for the inverter,and don’t split well into 2 strings. Learning as I go, should’ve consulted better
Tip for non-invasive detection of roof rafters under asphalt shingles for #solar panels installation:these are clearly visible on an early morning with freezing temperatures. Marked mine with paint and took a ton of pictures at 6 am today,before the sun rises and frost marking go
Received the Fronius Smart Meter, it limits the power export of my yet-to-build solar roof installation. Exporting power here is a bureaucratic hell, I will not subject myself to it by zeroing on the export. The inverter itself, a @froniussolar Primo GEN24 5kW due in 3 months 🙁
Sketched the south-facing slope of the house roof to identify where/how to fit the 14 Q CELL 355W #solarpanels I bought earlier (sized 1.68m x 1m), looks like I can fit 4 more panels in the future and split them into two strings. A good site, if you want to do that same thing in…
Sunroom we added to the back of the house last year totally pays off as it is the favorite place to hang out for all, dog included. The sun and greenhouse effect make it 24*C inside with no additional heating, while outside is below freezing -1.3*C.
