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-

Yes you can run 2x600W but they must be in parallel not series. You can always use an external MPPT like I have used and as Chris Louw is currently using to get more PV power to the battery. -

Hi All can you run a neey 4amp active balancer in parallel with a pace passive balancer with out blowing up the pace balancer. -
I will take a pic if I get a chance tomorrow of a shops alternator method they use to charge there batterys up in a short time between load shedding stage 6 . They use the grid to power the ac motor . If the ac motors going to be an issue due to generators limits then use a 250cc+ lawnmower or bike motor to drive the alternator if you a practical person you will always find a way around problems -

How are these "Fivestar" inverters? -

Here you go. Washing day here and no solar, so we used a lot of grid to get by -

Maybe the RCT Axpert VM2 1200VA if you can find one instead of the VM 1KVA. Just looking at spec sheets, your indicated inverter has 20A AC charge limit, and 500W of panel input, whereas for not too much more money the VM2 1200VA has 40A AC charge limit, and up to 2kW solar panel input, which is much better if you ever want to run daily baseloads from it while charging at the same time, or charge between loadshedding more quickly. -
Double check your load sharing cables (marked in green dashed lines). That's about the only thing I would think could cause an issue, besides a faulty comms board on one of them, except that the comms are set up if one identifies as HST and one as SL1 and as far as I know thats part of the comms board function. Not sure which part of the Inverter sets up the phase sync though and I think that will also be dependent on the load sharing setup. Have you run them in single setup, i.e. just use one Inverter at a time and tested whether they both work correctly as stand alone units? -

No the cable from the Pylontech goes to the Axpert. The Epever is set up to charge the battery to programed settings.There is a lot of parrameters in the program and controls beter than the Axpert.That is why I use the Epever as the master and the Axpert is running at 0.2v les than the Epever. The Epever does have a over voltage notification and switch of the mppt should that occur. I set the Axpert to 50A max so that the battery max Amp is not exceeded.The system is monitored by Solarassistant and running for more than 2 years without any problems. The benefits of this is that Axpert is running at a lower temperature. Power is avialable for more time during the day. Better flow of power when high loads is switched on.As we are running offgrid this is a great benefit. -
Would appreciate if other member can post charts of there solar production from centurion from 28 November. -
