2 strings panels at an angle

Trying to improve power from an existing roof installation.

We have an EasySolar II GX, which has a Multiplus II 48/3000/35-32 inverter plus a SmartSolar MPPT 250/70 solar controller.

We have 6x 320 W Trina Honey panels mounted on the roof of an ISO 20' (6m) shipping container. Because of the space constraints of the container roof, they are oriented about 20 degrees east of the meridian so get morning sun but lose it in the afternoon.

This is not producing enough power, so we have bought another 6x the same panels. We have 2 more 20' shipping containers at about 90 degrees from the original container (close enough that you could consider it one big roof).

Conventional wisdom seems to be that the new panels must be oriented exactly the same imperfect angle (azimuth and elevation) as the existing panels. Is there a better alternative?

I have seen some comment that two strings of panels back to back, facing respectively east and west, will not 'interfere' with each other so you effectively get separate morning and afternoon charge sessions from them.

Is that a better solution? How about having the two strings at 90 degrees, so facing respectively 45 degrees east of the meridian and 45 degrees west? What is the theory around this? What are the EasySolar's constraints?

Victron GX and battery LiFePo4 battery compatibility

I found on the forum the list of batteries with BMS compatible with Victron but it seems to date back to 2019, I think from 2019 to 2021 many things have changed, some products linked are not even on the market anymore.

I am intent on purchasing a Meritsun powerwall battery system to connect to my Victron quattro 10kw and Venux GX. I am concerned about compatibility.

The manufacturer of course says it can be connected without problems but that is of course the manufacturer's opinion.

To be honest, this company responds to my emails super fast, while another company like Pylontech listed won't even respond to a request for a quote.

Can anyone give me more suggestion?

connect BMV 700 by VE.Direct to EasySolar II GX- what more must I do?

I have already the EasySolar II GX and the BMV-700, both up and working but not connected to each other.

However I don't get State of Charge information in the Remote Console or VRM portal. The only place I get SoC is on the BMV-700 display.

Since both the EasySolar II GX and the BMV-700 have VE.Direct ports, I have bought a VE.Direct cable, hoping that if I connect them then I will start to see SoC remotely.

My questions:

1. Must I wait until the EasySolar is shut down before connecting the cable?

2. Once the cable is connected and EasySolar is back running, is there anything I need to do to get the two talking to each other?

3. Will connecting them in fact get me the benefit I am hoping for? Or is there something else I should be doing?

Small freezer causes overloads on EasySolar II GX

We have an EasySolar II GX which includes a Multiplus-ll 48/3000/35-32 inverter/charger- which should be able to supply 3kW as I understand it.

We also have a very small upright freezer, 85 L capacity, rated input power 90 W and consumption 0.73 kWh/24h (and we have meaured its energy draw at less than that rated consumption.

Yet, half a dozen times a day we get an overload warning from the GX device, which I can only imagine comes from the freezer compressor starting.

The only other devices we have connected are a caravan (major draw is a Thetford absorption absorption fridge, plus mostly LED lights and a laptop).

We want a bigger freezer, but I have to be worried that the EasySolar seems not even able to cope with the small one.

Or is something else wrong?

Horizontal mounting of Victron BlueSolar 75/15


I have a Victron BlueSolar 75/15 connected to a 120W solar panel. The 75/15 has no cooling fins at the bottom but just a solid flat metal plate.

The manual states that it should be mounted horizontally (as a general statement for all BlueSolar MPPT charging controllers) and there have been similar discussions in the forum around the larger controllers. However, is that really a "must" for this small controller using it well below maximum power spec?

Reason why I am asking is that I would like to mount it flat on top of my Peli case containing a LiFePo4 battery for camping.

EasySolar II - Network Reset?

Hey Victron Community,

We recently had an Easy Solar II installed at our house.
While trying to connect to the local WIFI, I have unchecked the "Create Access Point"... (yeah rookie mistake Im now aware of :) )

Ive tried connecting to the device via the LAN connection, but remember while browsing the settings prior to disconnection that LAN was disable (how it was installed).

So... Is there a means to reset just the Network Settings outside of the Digital Control panel?
I see there is a reset button on the Easy Solar II, and I have tried to search online for what this button does, but have come up short.
Is this a factory reset button? Reboot? or Network reset?
I do not want any of my other settings (charge level/battery settings) to be lost if possible.

What makes the most sense for my bus conversion build?

Howdy! I'm looking for a little help as I've figured out the beginning and end of my solar set-up but it seems like there's multiple ways to fill out the middle. I was originally piecing together a build based off of youtube but I like the idea of a mostly victron system where I can still cheap out on a couple of the components.

Here's what I'm working with so far:

  • 4* 400W solar panels (50.4V / 10.18A)
  • 24v Lithium battery bank

My panels are going to be wired in series so I've been eyeing up the EasySolar II since it seems capable of handling the 200v input from the panels. I will be using 120VAC and 12VDC in the bus so I need to figure out the best way to handle the 240VAC output from an easy solar II unit.

Alternatively, it seems like I could just get a 250|70 mppt solar controller and work that into a cheaper 2000W 24V inverter connected to a battery monitor and then the battery bank.

Will there be a 120v easysolar ii coming out? Is there a different product(s) that makes better sense for assembling my system?

Side question: how feasible/complicated/expensive would it be to integrate my 24v solar power system with the 12v system of the schoolbus?

Thanks in advance for any insight!

Correct MCB for AC-OUT1 & AC-OUT2

Good day,

I need some help planning my circuit breakers for the multi plus 2 3000va install.

here is my initial plan:


Please feel free to comment on any other issues you may spot.

CB2: Needs to limit to max 32A indraw to the inverter
CB3: Needs to support 32A + 16A from the battery/ inverter (hence the 40A, with abit of safety built in)

Now the spanner in the works is the AC-OUT-2 which I plan to plug into my electric geyser & air conditioners. I will need to put separate breakers on those outputs. Now im not sure how to do this? Cause in theory I need a 40A breaker for BOTH AC-OUT1 & AC-OUT2. However, I don't know how to do this?

If I put a 16A MCB on AC-OUT1, then this will be ideal for when running with no mains, but I couldn't use anything like kettle and microwave at the same time, even when there is mains available? alternatively, I can't put a 40A MCB on both AC-OUT1 & AC-OUT2 cause this will allow to much power to go through should the geyser and the microwave & kettle etc be on.

What is the correct way to do this? I cant come up with a solution that lets either use the full power but together they cant use more than 40A?

Question 2:

Are you able to control AC-OUT 2 from the VX controller, or is hard programmed to just kickout when power fails? (if I want to control that the geyser only turns on once the battery is full, will i have to use the relay output with a contactor?

Question 3:

Can I not maybe just connect the geyser upstream where the mains are? and just let the multiplus2 push its excess power back upstream into the geyser? Therefore not using the Ac-Out2 as I do not really need power assist?

Why can't a 12,8 V 20ah Lithium SuperPack battery be mounted on the side

The datasheet tells you to only use the battery in upright position. Other manufacturers versions of the same formfactor and capacity can be mounted sideways. What will happen? Degraded performance? Danger of overheating or explosion? Will it leek?

I plan to use these for powering fishfinders and lighting in kayaks, so upright is not always ideal.

Off-Grid - Multiplus II GX and Pylontech/Liontron

I want to build an offgrid system that mainly will be used during the summer.

Briefly outlined:

Energy generation, storage:

  • Phoenix Combi 12V / 1600W (we already have)
  • 4x PV panel 300W
  • MPPT 250/100
  • Car battery 12V 45Ah


  • Waterpump 1 phase 800W - 230V, 1h/d during summer
  • Intrusion detection (SMS module ca 5W, 24h/7d)

The system will be placed in a gardenshed.

The following questions come to mind:

  1. On a sunny day, will the power flow directly from the MPPT to the inverter?
  2. Plans to a future upgrade to a 48V system. I made calculations for the battery pack and the result was a 4x 12V-110Ah Gel battery combination. This was based on the rule which limits the maximum charge and discharge currents in regards to their expected lifetime. For this 48V system i need 3 battery balancers, which have their costs. My friend google found the Pylontech or Liontron LiFePo rack system. These systems have an integrated BMS. Can I use the Multiplus II GX or EasySolar II GX for the communication with the BMS of the rack battery? Or do I need an seperate GX device. And what power consumption is to be expected from this GX device.
  3. Do I need in regard with the future, buy the MPPT with ve.can functionality for communication with battery rack?
  4. Shouldn't Victron upgrade their MPPT's to higher voltages? I understand that more PV-panels on a string is a better choice. 250V seams limited to me for future design, if compared to AC-grid inverters.
