I know how to connect the LED pilot lights to show the status of Mains (Eskom) and Solar (Inverter). I already have them installed, but I want to add pilot lights to show which source is supplying power to the load via the transfer switch. I thought of doing it according to the drawing below because the neutrals are not crossing (two separate neutrals - inverter requirement). But I'm afraid that; 1.) this way might cause the neutrals (now) to cross, and 2.) both LEDS are going to "shine" at the same time anyway because each one is going to have a neutral and a Live fed (even when not switched). Please advise if this will be possible and how? Thanks so much

When i connect battery/PV to upperside 1> Positive 3>Negative is it correct? 2 and 4 s for load?

I am using a CBI Astute Smart Controller to switch on a pump that irrigates my garden from my JoJo tanks. I am well versed in IT and networking, but home automation is something I am just starting out with. i had the electrician install the ASC, connect it to the pump etc. I can now use the CBI home App to switch the irrigation on and off from my phone. So this proves to me that the App is seeing the ASC, and controlling it correctly. I can also use the countdown function on the app to start the pump in x minutes or hours. This proves to me that the App is handling this function, and sends a delayed “On” instruction to the switch at the appointed time.…

Are there any company that make-up comms.cable for Luxpower-Svolt stage1 battries.

Hi. I need some advice as my current setup is causing the fuses to melt. My hardware: I have 1x Synapse 5.0k inverter with the following ratings: Solar Charger Mode: Rated Current: 80A System Voltage: 48VDC Min. Solar Voltage: 40VDC Max. Solar Voltage (VOC): 145VDC The panels are 6x Trina solar TSM-545DE 19 panels. Their ratings are: Maximum Power (Pmax) 545W* Maximum Power Voltage (Vmp) 31.4V Maximum Power Current (Imp) 17.37A Open Circuit Voltage (Voc) 37.7V* Short Circuit Current (Isc) 18.47A* Maximum Series Fuse 30A Due to the 145VDC limitation of the inverter, the installer thought it well to setup the panels in a configura…

Hi I'm doing a lot of work around my house and am busy in the garden at the moment. I have buried a 110mm sewerage pipe around the perimeter of my garden, with a opening every 6m. I want to use this pipe as a sleeve for the irrigation pipe that runs from the borehole to the Jojo etc. I am also looking at putting in electrical cable for irrigation valves and maybe lighting on the fence. What type of cable is needed and allowed. 220v or lower voltage? Any feedback would be appreciated.

Revov to Victron comms I have a 2 X 5 Kva Victron setup with a Revov battery. 48 V 200A. It has a BMS48150 monitor but there are no comms cable to the Victron Colour control. Can I use a BYD to Victron cable. Also - if someone has a system, what are your settings?

I have an inverex mks 5kva and I tried connecting it to my laptop via ethernet cable and downloaded mpptracker in my laptop but nothing showed up on my screen. Do I have to do some settings? The communication cable came with the inverter had an rs232 port on one side and LAN port on the other (picture of which is attached below) and I did not have rs232 port in my laptop so I had to use an ethernet cable to connect my inverter to the laptop.

Good morning. Where can I buy 8mm sliding stainless steel T bolts and nuts in KZN? Thank you.

I have a small dedicated room where I'll be installing my inverters. If I use flat-twin-earth cable to connect the inverters with the DB's and main house DB, does it still need to be in trunking inside this room? Seems very unnecesarry as it is allready double insulated.

Neither CAN nor RS458 works with the inverter can somebody please help

Busy doing my budget for sizing and cable lengths. Its for lux sna 6000 2 strings of 7x550w panels 41x7= 287v 15amps max 30m run Seems like I can get away with 4mm2 but should I rather just go with the 6mm2?

Hi Guys I am looking for the 19" side bracket that fits onto the battery. I had mine on a table, but lost one set and now it is in a rack mount... Thank you

I found 3 (Installed) RCD`s in a week that does not break the neutral conductor when it (test) trip or even when switched of manually. according to SANS 10142 the RCD should break both conductors in a single phase sistem. With power off and using the bell, the neutral does break. I found this problem in 3 different houses with all 3 have new installations. Should the neutral also break or should it stay on to ensure a connection toe the Eskom star point?

I have this board laying around. Used it to program 2 way radios. And this type of connector.... I have connected, DB9 Pin2 (RD) to CP2102 TXD DB9 Pin3 (TD) to CP2102 RXD DB9 Pin5 (Ground) to CP2102 GND Solar Assistant finds the CP2012 But gives a CRC error. Should I connect the RTS and CTS pins? And lastly, Where should the jumper be on the CP2102? 3.3v or 5v?

Sorry for the abrupt question. The fuse holder between battery packs and inverter is large and unsightly so I want to know if it can be hidden in the trunking? I could not find a regulation stating otherwise, but maybe I missed it?

Friends of mine have a Sunsynk installation with a 12 x 550 W (Imax < 16 A, Voc < 700 V @ 0 degC) panel string. The installation is working well, as per expectation, but the fuse holder is running hot (~40 degC). The fuse holder is an Inge, rated at 1000 V, 32 A. The fuse is a 20 A fuse protecting a 6 mm2 cable. We've double, tripple, fourdouble-checked all the connections; there's no loose connection. Anyone else with experience of fuse holders warmer than expected? Most I've seen are running at 2-5 degC above ambient, which I expect due to the internal resistance of the fuse holder itself. But the 40 degC we see here is close to 15-20 degC above ambient…

Can anyone advise if solar cables and ac cables can run in same condute or ducting. I was always under impression that ac and dc must be seperated, but is that still the case with todays quality of insulation on cables. If this is a topic that was been discussed already in other threads, then please direct me to those threads.

Okay, the subject was a little dramatic but I am needing some eyes on this system plan to advise what looks wrong, and help with a few queries. Anything that immediately jumps out as an issue? Yes, I am using a fuse holder as a busbar as it works out cheaper (strangely!). Batteries are lead acid, 200ah at 48v. Eventually they'll be replaced with lithium. Questions: 1. Given the output of the panels, do I even need fuses between the MPPT and battery busbar? My (perhaps mistaken) understanding is that the fuse protects the cable. A 6mm PV cable has a rating of 60+a, which those panel strings won't push out, even in perfect c…

As per the title, what am I overlooking here? I have three series strings of panels each connected to their own Victron MPPT. I need to connect these to my 48v battery bank, so my thinking was a busbar/fuse holder/lynx. Considering price, and my system not being massive, I was leaning towards a fuse holder on the +ve and a busbar on the -ve. This is where I got confused! The Victron Busbar 250A 6P goes for around R900 while the Victron Fuse holder 6-way for Mega-fuse 250A goes for around R500. Why? I'd expect the fuse holder to be more expensive. What am I overlooking? Yes, an alternative is the lynx distributor or lyn…

Hi everyone! ☀️ I have an 8 x 550-watt solar panel system with two strings. Last year, I installed PV cables with 2.5 mm electrical cables. So far, everything has been working fine, but recently, load shedding in Zambia has gotten worse, with almost 24 hours of no power. 😫 I'm relying on solar power and batteries, but some of them are starting to give out in the early mornings. 🆘 I need to replace the PV cables to reduce power loss from the panels to my Luxpower inverter. Can anyone help me decide whether to use 4 mm or 6 mm cables? 🤔 Thanks in advance! 🙏 #SolarPower #LoadShedding #Zambia

Hi Guys What is typically the wiring sizes used in house wiring and DB wiring? 1) The size of wiring used in light and plug fittings 2) The size of the wiring used in DB for stuff like geyser and oven. 3) What is the best way to bridge wiring on DB circuit breakers when using the thick wiring (geyser/oven) when you need two of the thick wires into one CB or even busbar+thick wire? Best practice, what is safe and what not, etc. Is there a limit (regulations) on how much stripped wire can stick out above the CB, etc. Just need to confirm based on what I have seen in my DB.

Hi guys Stupid question. I see the Atess Combiner Boxes has parameters that can be adjusted. Is it possible to program/limit the breaker tripping load. I want to set the 400A to trip at 250A. Thanks

Hi guys Need a little help in calculating the bus-bar size for a project. (See image attached) 9 x 15000kva Victron Qautro's 4 x 450/200 MPPTs 3 x 60/48 Freedom Won Batteries. 1000A Discharge The red line is the busbar. Dark Blue Freedom Won Batteries Light Blue/Cyan Inverters Green MPPTs We calculated that a 1000A busbar will do the job but going with 1200A for safety. What are your calculations on this setup please? Thanks JAKE LAYOUT.pdf

Hi Guys please can i have your opinion in running DC volts through armored cable. Copper and aluminum. To be used to connect solar panels to inverter. 150m distance. 800v Some say that in armored cable induction will cause the insulation to deteriorate and short and burn after a while. Also more voltage drop in armored cable. thanks
