How much Weight is needed to hold your Panels in Place on a concrete Roof
Marcodp posted a topic in Solar Power,
Hi,
I have good friend who has a solid concrete roof on which he wants to install 4 x rows of 6 x 550w solar panels using A-Frames.
The main point here is that he does not want to drill into the roof and would prefer to use Concrete ballasts to hold the A-frames down.
Can anybody advise how much ballast (weight) he would need to use per A-Frame to hold the panels in place (not to blow away in the wind).
He stays in Cape Town where the wind is gusty and can be relatively stong, especially when the South Easter blows.
Below is a picture of the A-Frames he wants to use (note: this is not a picture of his installation....just a picture of the A-Frames)
The A-Frames will be placed 1.2m apart - can anyone advise how much weight is recommended per A-Frame?-

EVE Lf304 build
Pho3niX90 posted a topic in DIY Lithium Battery,
So I will be picking up my cells on Wednesday, I also purchased their Apex BMS, which is just a rebranded seplos.
I was initially going to buy a steel case and modify it from there, but has since decided to get a 3D printer, draw up some modular designs, and this will now be my project. From the mockups it is going to look good.
Will post my build log here.-

Saving on electricity after solar installation
raatkirani posted a topic in Beat Load Shedding ,
Hi All
Hope you are well. I had a question. How do you know if we are saving once solar is installed. I am not seeing changes on my electricity bill. My geyser is still on eskon but I have installed a timer to control when my geyser is switched on and switched off.
I have a 5kva inverter and 4.8kva battery. I run the house on solar during the day (switching back to eskom when using high wattage appliances like an iron or running multiple appliances at once when need to).
Kind regards
Deepa-

It's possible, but there aren't any at present. Have you tried the 175 V or the 100 V versions? -
Patched firmware versions 264.62 (200 V) and 164.62 (150 V). I assume you meant an update to the firmware.

@Sc00bs On my Aux port, under load when the frequency goes below 48 Hz, it drops out. the upper limit, I can't remember now. On the Grid settings you can adjust it, but not on the Aux / Gen port. I have an old 7.5 KVA petrol generator, and expect it to run up to 4 kW loads through the inverter. This is not possible through the Aux / Gen port, as it drops out, but through the Grid port is possible with opened parameters. Exceptions are when a motor starts up, it does still drop out if load is high. -

Hi, Someone can help me on how to flash the original WiFi dongle with esphome or tasmota firmware? I've try with usb-serial adapter connected to dongle PCB and 3,3 volt put in externally but it don't connect to pc. Any ideas? -
Hi @rylan76 I have a 5.5kva petrol generator connected to my 16Kw DEYE so it is definitely doable and will work. Is there any reason why you do not connect it to the Aux/Gen port, in my experience it is better to have the generator connected to it, not sure what issues @TimCam has had using it, was it just the voltage and frequency settings @TimCam? The Aux/gen port has a less stringent requirement as far as generator power frequency and voltage are concerned and rams up the load on the generator slower than when connected to the Grid port. The DEYE does have a box to tick when connecting a generator to the grid port that opens up the permitted voltage and frequencies. Not sure if the Sunsynk has this as well as an option. Do you have a Multimeter that you can check the frequency the generator is running at? I would suggest setting your generator at around 51.5hz, you want to adjust it so that when load is applied it is running at 50hz. One of the main issues that people have is that they set it to 50hz with no load, but when load is applied it drops down to say 48hz and the inverter disconnects. I did make a video on connecting to your generator which you might find useful. -

Is there a cost for the municipality to install them? -
Why not ask the municipality to install one of the Sienna enlight meters, they seem to work fine with small backfeed. I even have my Sunsynk set to 0w trickle feed and have not had an issue in the last 3 years. -

When I still had one it kept tripping the power when load shedding ended and it would start charging. Did that for months until one day it never came back. This is what I found inside : -
By Rouxenator · Posted
The past year I have helped a couple of friends and family on their journey to beating load shedding - and some going solar too. My recommended inverter has always been the SNA5000 from Luxpowertek. All installs were done by qualified electricians and CoC were issued. I only assist with the software side such as creating an account and setting up the inverter. Recently the customer code inf01 that I used for account registration stopped working. Can someone please assist? -

I am willing to bet good money your problems are caused by reverse flow. I see the Siemens meters have SRE: Significant Reverse Flow detection that is seen as tampering by the meter. -
So unfortunately mine actually goes into tamper mode and cuts the power to the home from Eskom. Only way to get it working is to have the city come round and give me a anti tamper reset code.

Sorry @Walnut, welcome to the Solar "rabbit hole". I'm also experiencing the same with my meter now showing "bypass". My utility has so far said as long as the "contactor" is not open, you shouldn't worry about it, only issue is that you may also experience an increase in usage from the grid because of the error on your meter. What error do you get? Apparently on my side the issue is related to the meter being installed incorrectly, resulting in the earth and grounding being shared or mixed somewhere and unfortunately, your electrician cannot "tamper" with the utility meter. As for the upcoming holidays I don't anticipate you losing power, but hopefully other forumites can also chime in.
