Switching on outside lights with alarm system
Fuenkli posted a topic in Lighting,
i would like the alarm system to switch on the outside lights if an alarm is triggered. The alarm system (Paradox) has programmable PGM outputs (12V 700mA) i could use to generate the required "on" signal. How do i use this signal to switch on the lights? The system would have to operate wireless.-

Deye v Kodak
Methuselah posted a topic in Starting In Solar? Feel free to introduce yourself,
Good evening everyone,
My finger is hovering over the button to buy my home solar system and I'd really appreciate some informed opinions. The basics consist of 12 x 340W JA panels and 2 x 2.4 kWh Pylons, with a hybrid inverter - and I've narrowed the choice to either the Deye (Sunsynk) 5kW or the Kodak 4.6kW Hybrid.
The Kodak would seem to be a South African product, appearing nowhere else in the world... That's not comforting. I believe that it is a rebadged Solis; should that calm my nerves?
What about their relative reliability? Supplier / manufacturer support? If anyone has experience to share I'd be very grateful.
Whilst I'm here, any thoughts on installation costs? It is a fairly simple install, panels on a single pitched corrugated roof with clear access to the main db and plenty of space for the inverter and batteries within 3m.
Your thoughts, ladies and gentlemen, would be valued.-

A new solar installation
RikH posted a topic in Member Installations Showcase,
We have a porch in the backyard that is covered with 18 260 Wp solar panels. They are connected to a SMA grid tied inverter and do their job quite well. Still I want to make changes to the system and slowly but surely changes are taking place. Here is why:
The solar is producing enough power for us the year round but that is only because we use the grid as a battery. In summer we have a lot of excess power that we draw out from the grid in wintertime. That is just how net metering works.
From 2023 net metering will be phased out gradually so using the grid as a battery comes to an end at a certain time.
The porch is a old steel construction with the panels bolted on to it and made (well they tried to make it) waterproof by using tonnes of silicone sealant. It's leaking all over the place.
So roughly the plan is to build a new wooden porch with room for the old 18 panels and an extra 18 340 Wp Trina's. New inverter and DIY a 30 kWh battery.
Here is the old porch:
Only the steel under cunstruction will remain because that's strong. Here are some pics of the build:
Next post will be the building of the new porch. To be continued...-

Need some real world advice
SvenA posted a topic in Starting In Solar? Feel free to introduce yourself,
So after much debate and conversations with people, my CFP said he did tons of research into his solar system and gave me advise which lead to decision to go for the following:
Either the alpha smile 10.1kwh system with its inverter and 3.5kw solar array from JASolar mono panels. Or a goodwe 4.6kw with the same batteries/pylontech batteries measuring the same power storage. My query is the following:
The goodwe can't be done in parallel from what I see, so does this mean i need to replicate the system again if I need more in the future?
Are there any regulations I need to be aware of when connecting all this to a prepaid meter In joburg?

His questions seems fair, no need to start a new thread... Wow, be careful @Wick, this kind of attitude will not be tolerated on Power Forum. @ebrsa has been a member of this forum for a few years already and his by no means a "newbie". Lithium's might be new to him, but thats why his asking... -
Sjoe, some Keyboard warrior going wild on this post. -
Hi, can you pls explain how the Axpert works with solar panels connected, I would like to know if the panels always charge the battery and the inverter will convert the power in the battery to AC and if the batteries are full do you covert power from the panels or do the system always convert from the batteries. Hope it makes sense. Thanks -
System I had installed for load shedding. -
Grease and Seals deteriorate with age, hence bearing failure! For this reason you'll be lucky to find a car manufacturer that will guarantee your car for more than 5 years. Nevertheless, a little maintenance can make your car last just about FOREVER, same is true for turbines. I have been donated two turbines that were "faulty". I did some basic testing on both and found no trouble on the wiring of either unit. The one unit had a seized neck bearing, bit the slip-ring was still perfect. I removed the bearing and sourced a suitable (better quality) replacement from my local bearing wholesaler. From what I could gather, both machines were "China-Specials" I sold one unit at a very reasonable price and donated the other to a friend of mine where the machine is serving him just fine! The cost of bearings for Repair/Service was less than R 300-00 per machine!
