Multiplus II - PV Enphase microinverters on AC-out-2

MP2 48/5000/70 - GX

I have some original Enphase m215 micro-inverters connected to AC-out-1 which I manually switch on and off to prevent the m215's pushing the voltage too high when the batteries are fully charged. I have tried setting the PV inverter assistant, but I think the m215's are so old they cannot limit their output on frequency shift.

As this whole system is off grid I would like to connect the m215's to the currently unused AC-out-2. I would like to know if I can configure the internal relay which switches AC-out-2 on/off depending on the grid being detected at AC-in-1, so that it switches on/off based on battery SOC.

Any advice would me much appreciated.

Does the AC Output #2 shut off on the Multiplus 2 24/3000/70 like on the Multiplus?

AC Output #2 on the Multiplus 24/3000/70 shuts off when the batteries are charging. We are using the Multiplus in an off grid system for household power. It doesn't appear that can be changed. Does this apply to the Multiplus 2 or is AC Output #2 hot continuously as is #1?

by pass AC input to AC out 1,2 when inverter fails

Hello all I am wondering if there is a setting using the programmable relay or other relays in the inverter that can be helpful to do so :

bypassing the AC input 1 to the loads those are connected to AC out 1 & 2 in case the inverter fails or shutdowns due to some errors.

RCD breaker for Quattro 10K

I'm looking for recommendations on 125A/240VAC two pole RCD/GFCI breakers. It seems while ASI produces 125A breakers they stop at 63A for GFCI protection. I am in the South East US.

I see lots of mention in the forums about using a RCD but never a specific brand/name in conjunction with the Quattro 10ks.

common neutral busbar AC OUT1 and AC OUT2

Can I use a common busbar for the neutral wire of AC OUT1 and AC OUT2? In the diagram they seem to be connected inside the multiplus 2.

I have parts of my home wiring sharing the neutral wire but I want some loads to be supported by battery and some not in case of outage.

AC IN neutral will be separate.

Thanks

Hi there


I have a multiplus 3000/230v and I do not manage to get any voltage on the AC Out 2 when connected to the grid.

Is there any magic to get this to work??

phoenix smart 24/3000

hi all,weve got a pheonix smart 24/3000 inverter, just wondering what size cable to get for the AC output, in the manual is says 26a short circuit output i cant see any other mention of AC output, also the output screw terminals arent very big so i doubt if cable bigger than 10mm2 would fit, thoughts from anyone who has this inverter

AC-out-2 Doesn't output while charging the battery.

AC-out-1 works and the batteries are charging however while charging in bulk the AC-out-2 stays off.

Quatro 5kW 110 V AC output 2 not active

Hi team,

I am looking into a strange item. The Quatro is connected to shore power and to a generator, the AC1 is going to my ship and I planed to use AC2 for the watermaker and heater.

All is setup and I can use the AC1 output. But I do not see the AC2 output.


I do not have the interface but I have a GX connected to the victron network.

How can I activate the AC2 and set limits to the input? or is this AC2 broken and should it always be activated? or is it only working when AC2 input is there and not AC1 input...




Thanks

AC OUT 2 assistants

I have an AC inverter connected to AC-Out-2 on a MultiPlus-ll.

A generator is going to be connected to AC-In-1

I would like to turn AC-Out-2 off when AC-In-1 is active and when Aux-Input-2 is open due to a BMS high battery voltage signal.

AC-Out-2 turns off when AC-In-1 is active but AC-Out-2 will not turn off when Aux-2 (BMS high) is open because it is still being driven to stay on by AC-In-1 not being active.

The idea of this is to avoid using a contactor on the AC inverter.

Can these two be done in combination?

Hopefully makes sense!

Using AC-out 2 while ignoring AC-in.

Dear experts,

I'm using a 48V solar system in an area where there is sometimes grid power. Because in general my solar capacity is sufficient for my loads, I set the virtual switch of my Multiplus to only charge when the voltage of the batteries drops under 50.0V. Unfortunately AC-out 2 appears to be dependent on the same AC input relay and cuts the power when AC-in is ignored through the virtual switch. However, I would like to be able to use my AC-in via AC-out 2, for certain equipment, while not charging the batteries. Is there a way to program the Multiplus for this or should I just make a bypass of the AC-in before it enters the Multiplus?


Kind regards,

Mark

1phase in (charge) , 3phase out _charging not working

Hi,

I'm configuring a system with 3 MP2 , in a 3 Phase out setup. As per the instruction video's etc. this should not be any problem, but the charging doesn't start when the phase comes up at the master L1. The 3 phase out put works fine.

So I have checked the forum, and checked the training video's again.

In the training video's its shown in the following diagram. The inputs of L2/L3 are seemingly connected with a 0V, therefor I tried to have the null connected to all three inputs, this didn't help.

[image]


Anybody an idea what I have done wrong? Are the connected nulls at input needed (electronically I can't imagine it's needed, but the screenshot shows something there)?


Best regards,


Emiel

Paralell multiplus ac-out breaker tripping

Hello,

I have 2x EasySolars 24/3000 (basicaly Multipluses) configured in parallel.

The problem is that from time to time the main ac-our breaker tripps (one or the other inverter). How can I identify the issue?

Seems sporadic to me with no special events..

Thank you!

Multiplus 24V 3000, AC 220 V output consumer board configuration

Hello

on the attached schematic there are two AC outputs. I am confused as to how the daily consumers should be connected. I do not want some consumers on AC 1 and others on AC 2. I have designed 6 AC circuits needing separate MCBs and i need them to be supplied from either shoreline and the inverter output seamlessly. Can anyone help my understanding of the two AC outputs please? Thanking you all.
