These WiFi gadgets give the illusion of convenience.

1. Disconnect from normal WiFi
2. Request connection to aux WiFi for the device
3. Start the app
4. Switch the device
5. Close the app
6. Disconnect from aux wifi
7. Request connection to normal wifi

I prefer Bluetooth devices. It doesn't require fiddling with existing WiFi connection and works if WiFi isn't working

No it's not like that.

The only time you connect directly to it over wifi is the first time you set it up and give it your local wifi password. From then on its on your local network. So just click on app and switch on or off.

Much quicker than walking 50m in the dark or rain to unlock the power room door then say hello to snake switch pip off . Then lock power room say goodby to snake and stagger back in dark or rain.

Like I said the divices also have built in RF receiver so 4 button garage door style learning remotes or wall plate switches with RF can also activate the same switch as well as wifi.

Bluetooth is only good for very close connections and has many restrictions over
Over wifi.

What bluetooth device do you recommend
Think i'm liking bluetooth... wifi can be kinda slow to respond and if you loose internet switch does not work. But it's way cool to control from any where. Hard to beat sonof wifi switch prices!!!

Again,
      It makes no difference if you loose internet. Your not controlling it over the net you can control it over your local wifi. Any place you have a local wifi network connection (as in you can see your wireless router or repeater you can control it (you don't have to use Sonoffs online application) as that would shoot out to a server then back again. 3rd backup is the 430mhz RF remote that is built in again no need for internet.

Bluetooth is flaky and only good for 10m or so. Even then it's not that flash.

I more or less have WiFi connection anywhere on my 29,000m2 property so no issue connecting.

If you want to know how to flash the unit to run 3rd party software there is easy steps how to do it on Utube.

Pretty cool.
Arduino coding is a bonus.
RF remote not in the model you gave link to, must be another upgrade model. Sounds like what you are looking for SJ.

What I'm trying to figure out is how to effectively reduce the load requirement for the pips power saving mode. At the moment if I open the microwave door the bulb lights up then the inverter goes back off. Maybe a hall sensor on the line side, feeding to analog input of a nano which triggers a ssr connected to the inverter switch?

Yes sorry your going to have to pay an extra 60 cents - $7 for the one with both WIFI and RF remote Image

https://www.itead.cc/sonoff-rf.html

Perhaps you could make use of another unit they sell

that has on board power consumption monitoring for $10. I haven't looked into it much but there could be a way to get it to switch based on one pips measured load. there is always some way to tweak things if you get creative.

Hi,

I tested your software and look and works great for parallel inverters.
I have a three phase system made by 3 inverters and i can read only the first one. Could you be so kid to help me with a modificated software solution to monitor all three ?

hi !
i already use sonoff to switch on-off relay to use surplus power from 4048, twilight switch and external fan switch.
First of all you need use LUCIBUS, that is a software i made to display
situation of 4048.
sonoff and VIATOR (synoptic led viewer to display load situation) are connected in wifi to LUCIBUS that sends info through wifi router.
these are links

LUCIBUS info (english) :
http://www.homoandroidus.com/lucibus/index_en.php

VIATOR info (italian only ---> please use Google translator) :
http://www.homoandroidus.com/viator/viator_2

SONOFF info (italian only ---> please use Google translator) :
http://www.homoandroidus.com/lucibus/sonoff

sorry for only italian Language for some infos.
I'm working hard to translate. i hope all will be ready soon

VIATOR ver. 1 was present in MAKERFAIRE Rome - European Edition 2016
http://explore.makerfairerome.eu/poi/Exhibit_353
note : click top right corner for english
note 2 : that is the Ver.1 of VIATOR. Ver.2 now works with D1-MINI

What software are you referring to here? If you mean the firmware inside the inverter, then I do not think it needs modifying to provide what you want. There are already the QPGSn commands (QPGS1, QPGS2 etc), which are described in the Protocol Manual.

I will try the solutions . Image

The biggest problem of these systems is monitoring the , as long as you see how they work , you can do maintenance on them and also save money, I am a telecom engineer and I am am used to monitor and analyze performance on power systems ( in telecom , this is the reason that chose 4048)

I hope that's a typo, and you haven't put the patched firmware into a 24 V system (2 x 12 V). Presumably you mean 2 strings of 4 12 V modules.

I'm glad to hear that the batteries are happy. It's also good to see that at least some lead acid setups need the fix, it isn't just the radical hippy lithium worshippers Image that see the problem.

hi lopez !
no, i'm sorry Image
lucibus creates its own mdb database and it works exclusively with it.

in Italy it is rare that data is shared, because it could be used for different purposes and therefore almost all people do not share or upload them.

Solar Junky wrote: Hey guys you got to help me have tried every thing to get the db9 cable to work??? ... any help would be AWESOME!

Here is something that caught me recently. There are a bunch of fake Prolific USB to serial converters out there, and the drivers have recently (in the last year or two) stopped supporting the older models (including hopefully for them all the illegal clones). I ended up buying another one some years back. and marked it as bad, but the writing wasn't terribly clear, and I forgot all about the issue. Recently when I went to grab my Prolific, I found the old one, and didn't realise it.

Maybe this isn't your exact problem, but it caught me, so it may catch others. The symptom is that when you plug in this bad device, Windows sees it, and you get the happy USB sound, and it loads a driver. But that driver crashes, and no software other than Device Manager can "see" the comm port. This is what Device Manager shows:

Image     Image

There is a tiny yellow triangle in the corner of the small icon; I've zoomed in to 150% of normal to show it moderately clearly. If you double click on the Prolific entry, you get the second screen. Here at least it's onbvious that Windows isn't happy with this device. (BTW, it can still be used successfully on Windows XP, but not Windows 7/8/10). Click on the Detail tab underlined in green above.

Image     Image

Now choose Hardware IDs from the drop down Properties list. You should get something like the second screen shot above. If you see REV_0300 as above, then it's the bad device, and you won't be able to use it with Windows later than XP. (Perhaps if you find a really old driver it might work for a time, but Windows will "update" the driver for you soon. You're welcome.) If it says REV_0400 or later, then you have a usable device.

Solar Junky, hopefully you saw my post about the flash tool only being able to see comm ports 1 through 9 (COMM1 to COMM9, not COM10 to COM99). It's right at the end of a page with lots of other threads being discussed, so it's possible you missed that.

"but Windows will "update" the driver for you soon"
You can stop windows doing this I use the old Prolific USB-232 on windows 8 & 8.1 with an old driver it has proven very stable
The best way to connect to the PIPs is the HLK-RM04 it gives you a virtual com port on your machine.

Hello EveryBody

First of all, i'm french and sorry for my poor English :-(

I'd like to give many many many thanks for this incredible thread about this voltronic inverter ! It's full of very greats informations and it take me 2 full weeks to read every pages :-) :-) :-)

The subject : How to write a gateway between the inverter and watchpower with a raspberry (to target small price) to inject the inverter informations (battVoltage, PanelPower, etc... on my Europeen home automation bus system KNX, to manage the power loaders (for example to make cold water) when the sun is full or not. More generaly : how to use the excedeed sun power when the batt is full ?

So i started on august to develop with my dev boy, a Raspberry Native C++ application with this scopes :

- The raspberry must communicate with the inverter with Serial or USB port (it was the more difficult part of coding).
- The PC with watchpower must be connected on Raspberry with a cheap USB to SerialTTL to target the ACM0 IO port. Bluethooth will be disabled on PI3
- If WatchPower is not connected, the program must run on a standalone mode to send commands on the inverter.
- a xml config file for the KNX object configuation, because of many possible GroupAdress Configuration already instaled.
- a future TCP socket et HTTP communication, to target an IOS and Android app, on LAN mode and far away a cloud mode to manage your inverter when you are on the beach !

I've got a MPPSolar 3MPPT (MST version 75.1), and I discover some undocumented commands to get the values on Panel2 and Panel3, but the dev was firstly done on a simple MKS with 72.4 version

The TCP and HTTP are still to code, but we've solven all the rest of this PowerManagement Program

For the future, i target the put LUA scripting, and a TouchLCD 7" screen to see the information easier than now :-)

and many many other functionnality in this project for the future like BMS, but i prefer to stabilise what it done for now.

finally, I'd like to find some folks to help me to debug this first alpha version (I can give a IMG of an already installed System for PI3)

If you have interested, just give me a message

Many thanks.

pip 4048 grounding question???????
Have my inverter, batteries, negative side of the solar input grounded to the same ground grid uses. been like this for a long time so kinda forgot about it.... How Should it be grounded or will it be ok??? Have the positive side of solar input threw breaker & Negative fused with ground on inverter side of fuse.

The inverter itself will be grounded via the AC in cable, or if no mains connection, it should be grounded via the AC in or AC out earth.

I would not earth the battery or the PV, and certainly not both. I'm pretty sure that there are models [ edit: of the PIP/Axpert ] where connecting the PV negative to battery negative would cause the MPPT to be bypassed, so the panels would be continuously charging the battery and at poor efficiency. I suppose it's possible that it's doing that now, though I would think that there would be clues as well as alarms if that was the case.

So I would definitely not earth the battery or the PV array. Just leave both of them floating. You can earth the frames of the panels, but usually that's not a requirement when the panels are Extra Low Voltage (ELV, <= 120 VDC). Of course, that's completely different from earthing the PV input (negative or positive).
