stoic

Managed to get one step further. I successfully used the quick configure app and the LED app to set up three phase by eliminating some things. Now i can start up the system with both AC and DC inputs.... the three inverters runs for about 40 seconds, then all three switches off and the "Inverter on" and the "Bulk" light flashes, while float stays lit... unfortunately the LED app does not have that one

K... so i got it working without switching off I used ve coonfigure to set it up as three phase. now.. if i am running off solar and battery power, everything is 100%. but as soon as i switch on mains, all three inverters switches off and the overload light flashes on all of them

I can successfully connect inverter one to inverter two, but not 2 to 3. as soon as i do it inverter 2 and three clicks and the "inverter" on and "bulk", "obsortion" and "float" LEDs flash, and there is now power on their outputs

haha ... i got a bypass switch ... damed if i knew how to wire it. does anyone have a diagram? I have three phases coming in and a three pole changeover switch.

each inverter has 2 ve.bus ports So i connect from inverter one VE.bus to inverter two ve.bus. then from inverter 2 ve.bus (2nd one) to inverter 3 ve.bus. then from inverter 3 ve.bus (2nd one) to venus gx ve.bus is this the correctway? can i then switch on the inverters after i've done this? or do i need to program it first. ... i'd like to do it step by step

Prices are a bit steep though... i bought three of those a few weeks ago for R13,241 each.

This video gives some info on MPII and MGII, the first part of it is explained that it is just a name change.

also worth noting is shower times ... yes... it takes the same amount of energy to heat water to a specific temperature, but what is lost sometimes is that if you shower for 5 minutes a day you will only be using gas for that 5 minutes and only heat up say 50 liters, where as if you used a normal grid geyser it would have to heat up 150-200 liters per day for you to only use 50 liters.

UPDATE Managed to get the vicron connect to connect to my MPPT (USed a different Device) Question: I've configured the MPPT as follow: https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom. The only section pertinent to the charger and batteries are section "4.2 Charge Settings" In fact... the only settings i applied was 4.2 as the rest is not apparent on the app. I've switched off my CC and batteries after i applied the settings to make sure i get some feedback from the forum before i switch it on and let it run.

Hi there, So i have the entire system installed now. I have a few questions: Victron Connect - For some reason i cannot pair with with my Smart Solar MPPT 250/100-tr, it is stuck at "Connecting 40%". Three phase Daisy chaining - RJ45 - How do i need to wire it. Is it the usual way or crossover? Where does these cables connect to on each of the inverters Right now I have the three inverters connected to AC and i have disconnected the Battery bank from it. Even though i have three phases i can still run each inverter on each phase independently, and i have no three phase equipment running off the inverters. So at least i will have power for the night. Should i be concerned bout anything seeing though no setup has been done yet? I need power to research so i hope i can run the three inverters as is for now without battery and solar, just off mains. @plonkster - Tagging you as you are a victron expert. but anyone else that can help, please do.

welcome

...as if electricity is not complicated enough already... and now you go an add riddles to it...

Can anyone explain the difference between a DC breaker and an AC breaker? I did not even know there is a DC breaker

Poor Joe ....

don't do this too me... please..

yes... nothing connected yet, i am only getting my charge controller and inverters this week. Right now all panels are only connected to my combiner box. And if you say its normal, then i suppose i did a good job and limiting voltage drop

just to add.. the panels are fixed at 22 degrees, and facing true north. My concern is, my CC is rated at 250V and i am worried that when i do get perfect conditions and some cloud edging that it might exceed the CC's limits

So my panels are up and are connected to my Combiner Box and today i was a bit confused. According to my specs, i should expect 31V @ 8.88A on a good day from each panel. I have 6 panels in serie, which means the voltage should be about 186V, however, during the day i am constantly sitting on around 215V it goes up or down by a 5-10 volts depending on cloud cover. It is now 5:30PM with heavy cloud cover and I am now reading 192V from each string which is still more than what it is supposed to read at best conditions. So i did read about the cloud edge effect, but there was no clouds when it was stable at around 215V. When ever a cloud did come over it would drop by a few volts. I am just stumped that the voltage is so much higher than what the panel specifies. ... oh yes... and i ended up using 6mm wire.... max length of one of the strings is 6 meters.

Unfortunately i have three inverters. One on each of my phases... so i beleive will still need a busbar to split the power over the three inverters. I am however using one CC for the three batteries in parallel

hey TTT, thanx for the response, I kinda understand that building insurance is generally waaay cheaper than content. Maybe i should not have used phrase "too good to be true" . What i was trying to find out is: Should solar be listed under building insurance? Cause it is quite susceptible to damage theft, lightning strikes etc. the fact they they did not ask for an electrical clearance certificate also makes me wonder a bit. It just feels too cheap.

My panels went up this last week, so i decided to see if i can insure them. Even though i do not have the rest of my equipment yet (due to festive season closures) i decided to include everything i purchased in the quote request. I am with outsurance (building and content), so i dialed them up this morning to see how it will go. I specified all my panels, charge controllers, inverters and batteries and i was asked two questions: Will you be powering your house, or just geysers? i said the entire house. Are the panels on the roof? I said yes, mounted on the roof. Outsurance said they will call me back in 10 minutes, which they did. The outcome.. Everything will be falling under the building insurance, they upped my value by an additional R170k and my premium increased by R26 p/m. Now... i know they are great, but damn .... R26 p/m extra on my premium is not that bad. Do you guys /gal? think this is too good to be true, or have you had similar experiences when insuring your systems?

I have 3x US2000B pylons. and i will probably add another 3 in June. I see that the inverter i got accepts 38-66V so do i need to connect these three batteries in parallel to stay within that limit? This also means i am gonna run at around 150A for just three batteries and if i am going to connect three more i am going to sit at around 300A. This too me sounds a bit scary. but non the less. What is the best way to connect the batteries in parallel? Looking at my image below the positive from battery three to the buzbar is seems net longer than battery 1 to buzbar. Will this cause an uneven charge? Is there a better way to connect this, or is this standard?

now that i think about it... do i even need a combiner box, seeing though the MPPT can take three strings? can i not just connect my three strings directly to the MPPT? sorry... it only has PV possitive and negative

Combiner box to MPPT is at most 3m Array to combiner box will be +/- 10m (that is from the furthest panel) in future i would like to expand. but i will first increase my battery bank to about 12 kW before i do this.

Hey guys, I'm sure you've heard enough from me already. Can someone please make a suggestion on how i should lay out my solar panels. I have: 18 * 275W Canadian Solar panels Victron MPPT250/100 3 * US2000B 3 * Multiplus II 48/3000/35-32 - They will be running in parallel for three phase Now, at first i thought i had it covered. I tried to go as high a voltage i can 6 panels in series, giving me about 180V and then string three of these series in parallel giving me about 27A and 180V, but then, @plonkster mentioned that those pylons need around 80A to charge. Now i am not sure if i need to give that from the solar array, or if the MPPT will manage my 27A, 180V and automatically deliver the 80 amps required to charge the pylons. Can someone please comment and give some guidance? Is it correct of me to try and get the voltage as high as possible? The cables i will be running will be no longer that 20m from the furthest panel to the MPPT. Lastly, based on my arrangement, or a better suggested arrangement, what thickness cable should i get? I was at a solar store today, and they wanted to give me 6mm copper clad flex cable, i had my doubts as i believe copper clad has higher internal resistance, also, i am not sure if it will handle the current.
