Multiplus 12|3000|120 AC-Out-1 wire size

Multiplus 12|3000|120 AC-Out-1: 75A possible. AWG 6 recommended.

AC-In says to use three-wire cable, AWG 6 gauge. Rated for 50A.

I've seen 6/3 cable say 55A per conductor, so is 6/3 cable sufficient for AC-Out-1? Or use three AWG 6 wires, or a lower gauge like 4/3?

Thanks!

Convert IP65 extension cable to SAE?

I have an SAE quick connect mounted to the outside of my battery box for when I want to plug in the solar panels without accessing the battery itself. It has a fuse between the quick connection and battery.

What I was wondering is if I could convert the Victron 2M extension cable into an SAE connector so I could use that same SAE quick connection when at home and plugging in with the IP65 charger, again so I don't have to access the battery but still being able to use a connection I already have set up to the battery


Would converting a Victron 2M extension cable to SAE connector create any problems for charging normally with the IP65 charger?

wire sizing for connecting flow meter to Venus GX

Hello,


I have purchased a flow meter which can be connected to the Venus GX. Unfortunately this flow meter is around 50m away from the Venus GX. I am aware that the wiring will need to be of a greater diameter due to voltage drop.

Does anyone have an idea what the diameter of the cable should be? From a number of calculators it seems that 1.5m2 cabling is sufficient.

Thanks

Lynx Distributor Usages Clarifications

Hi All, my first time with Victron products and Solar Energy. Questions about Lynx Distributor. Considering that has 4 slots fused.

1) May I connect the whole system in One Lynx Distributor Unit?.
Example;
Slot 1: Multiplus-II 48/3000 (Fused)
Slot 2: SmartSolar MPPT 250/100 (Fused)
Slot 3: Lithium 48V Pylontech US3000 (Fused) (3 parallel modules connected with cable kit 120A/2000mm lenght)
Slot 4: Venus GX (Unfused as brings its own in-line Fuse)

2) Fuses sizing should be MEGA 125A for all 3 Slots? (i.e. Littlefuse MEGA 125A/58V for 48V)

3) Is there a minimum lenght for Cables of Slot 1 and Slot 2, I have available AWG2 35mm2 nominal cable (33,6mm2 actual section). For Slot 3 cable kit size came Pre-Fabricated.

Please if you see any safety issue advice, this is an Off-Grid system. 3000W Panels Array (4series x 2 strings). (SmarSolar is oversized for future expansion duplicating whole system)

Thank you,

Bye

Guidance on Multiplus II 3000 fuse and wire for Pylontech batteries

Hi,

Little confused about battery wire requirements and fuses for using the Multiplus II with Pylontech batteries. It would seem that you have to use Pylontech branded cables as the batteries have a proprietary connector on one end to go into the battery. I can see in the manual it recommends 35mm2 cable and a 125A fuse. My dealer gave me a 200A fuse, I read on here, someone else had their distributor give them an 80A fuse. Confusion number one!

Confusion number two, I can't see what the cables provided by Pylontech are in terms of thickness, there doesn't seem to be a rating on them. But like I say, they have a special connector on them so it would seem you have to use them? Confusion number two!

https://www.ebay.co.uk/itm/2m-Long-Cable-set-Pack-Pylon-PylonTech-US2000-Plus-US3000-Phantom-Solar-Battery/253792544671

Then finally, I have seen two installers here in the UK, who don't have a breaker, isolator or fuse on their installs between inverter and battery. Mind you, one of them also puts the batteries below the inverter, which the manual pretty clearly says not to do! Confusion number three! See pics.

Any help advice, particularly from someone who has Pylontech batteries would be much appreciated.

Many thanks,

Gareth.

Pylontech battery cable spec

Hello,


Can someone please clarify the following:


The Pylontech 2m external power cables (both + and -) is labelled 4AWG. The Pylontech US3000 manual (page 12) rates this as a 120A cable. AWG 4 translates to a 21.2mm2 cable with a current carrying capability of 70A at 60 deg C. (https://en.wikipedia.org/wiki/American_wire_gauge)


A Pylontech US3000 battery (page 4 of manual) has recommended charge/discharge capacity of 37 A. This cable should work fine with a single module. However 2 modules in parallel will double the current capacity while voltage remain at 48V. Are we really using a 70A cable on a 74 A supply source? Obviously the max current per single US3000 is much higher.

The Pylontech cables does not appear to be a copper cable. The wire strands are silver.



Thank you

Jean

Suitable Circuit breakers

Hello,

Im just after some advice on a suitable circuit breaker between the panels and the mppt

I will be installing 3 (potentially a 4th in the future) Victron poly 175w panels in series and a Smartsolar 100/50 MPPT but am unsure of which circuit breaker to install between the 2 in order to isolate the panels if need be and also for safety.

Given voltage will be up around the 72 mark what would you suggest? With 4 panels it will be around 94v


Between the MPPT and batteries would it be advisible to install a 60 or 70amp medium duty thermal circuit breaker?

Phoenix inverter (12v 3000w 230v) cable size.

Hi, could someone be kind enough to confirm the battery to inverter cable size on a 12v 3000w Phoenix inverter? The manual states it it should be 90mm2, this seems awfully large considering the carrying capacity of this cable is 500a, the inverter will never be used continuously at full power and the cable run is around two meters, I currently hold plenty of 70mm2 cable and thought this would be sufficient given a carrying capacity of 485a. I look forward to hearing some feedback.

Thanks in advance.

Solar cables size to MPPT . Combiner ?

9 x 270 w solar panels in 3S 3p

Max 42v - 9a

MPPT 150/100


I generally use 10awg (2,5mm) solar panel cables . This system has 9 panels in 3 series of 3.

If i wire and use Y MC4 (without a combiner box), I could have only 1 pair of solar panels cables from the roof to the MPPT which is 90 feet away.

This pair will roughly support 120 v and 27a at max. I am a bit worried with the size of the cables .

Would you think 10awg is large enough for this ? Or would you consider preferably:

1/ a combiner box close to the roof and then a larger cable to the MPPT ? May be 6 mm.

2/ or leave 3 pairs so each will be 120v/9a which is more acceptable for this size of cable ?

Thanks for your input.

Series from 220ah to 440ah .90 cm length

Busbar to battery Positive and negative cables 125 cm length

It appears that I am in the neighborhood of a 35mm2 or 50mm2 size. Is it wise to err to the 50mm size of is 35mm good.

I have the option of connecting another 17 panels to it that are on enphase M215 inverters on the back of each of them, the issue is they are 200 meters away and there is no space to move them closer and refit them. If the panels are running flat out i would get about 14 volts drop, would the two devices work together ok like this? The amount of power i would get if the were running flat out is far more than i need, just like to have the extra for the bad solar days. Anyone got any experience they can share?
