Really? So, as long as the inverter switch is OFF when I turn the battery switch on, there is no risk to damaging the inverter? Then, I just turn the inverter on after turning the battery on? I thought purpose of precharger was to prevent a surge when turning the inverter on. My current...

Can you share what is inside with parts list? VERY clean solution! I like the indicator light to show the voltage difference. Does the light go out once the voltage is equalized/capacitors are charged?

Gotcha. I have a wake-up button (I have to swap it in after removing UART Bluetooth dongle - v2 BMS limitation) on my Daly BMS for that situation.

Is the 15V DC power source required for a 12v Multiplus II and not the 24V Multi?

I like this. Contained.

Thanks Skypower for a smart solution that fits my pocket weight $$$

This appears wired to bypass the Battery on/off switch and to be activated only when the button is pushed to precharge. I assume I can set up with permanent connections by connecting to the in and out studs on my battery switch and put in a small plastic box/container on my power wall next to...

Is this always connected? If so, are similar 'DC surge limiters/battery protectors' from Victron and others sufficient for less than $280-300?

My Aims solar charge controller installation manual requires battery connection before PV breakers turn on "to protect the solar charger from damage". It appears to require the battery power to operate properly. It shuts down when/if my battery goes offline (I assume to protect the solar...

In my current RV solar power wall, I use a 600amp blue sea rotary switch as a quick connect between the Lifepo4 battery and the rest of the 24vdc system (inverter charger, solar charge controller and secondary 24vdc charger). I turn the blue sea switch "ON" before I switch the Aims inverter...

I am currently reaching out to folks that are writing Venus OS drivers to interrogate using TTL Communications protocol. Most are BMS query/interrogation and would seem to be adaptable to interrogate Aims inverter/charger using the protocol documented (attached). Hoping to make some headway on...

If you have the SA contact info, I'll reach out to them with the Aims TTL Communications protocol document to see if they can adapt to support. I'm also checking with others to see if anybody can write or adapt an existing Venus OS driver to query the Aims inverter RJ45 cable connection using...

Can your driver be adapted to run in Venus OS (on Raspberry Pi 4B) to interrogate inverter/charger from Aims Power and display this info in the AC In/Out information on the Venus OS display interface? I have TTL Communications protocol document from Aims that describes the messaging (Query and...

This is impressive. I'll check out Iotawatt also.

Can your driver be adapted to interact with any TTL device using TTL communications protocol? I am asking as I have a document from Aims that describes that implementation of TTL with the interactions defined.

Thanks. I'm printing the info.

Looks like I would need to write code. SA doesn't talk Aims inverter/charger.

Has anybody explored or set up a data logging hat on Raspberry Pi 4B to collect data from an ethernet cable? I want to log data from an RJ45 cable that is attached to my Aims 6000watt inverter/charger. The RJ45 currently feeds a proprietary Aims display. My goal is to monitor/track data...

Agreed. I see the SolarEdge compatible solutions have a $$$ premium that hurts my wallet :D

I am also considering a 'less DIY' solution around my Aims inverter/charger and an enclosed rack of six, 24v, 5kW Lifepower case power cells at $1,500 each (just saw a price drop to $8.1K). Considering it would be a 30kW storage solution, it would be nearly 4 times the capacity of the $7-10K...

To keep all things equal, I would carry on the connection in parallel add the two 100ah batteries into the mix of 4, 100ah batteries in same configuration for a total of six. Do the Li time batteries have internal BMS?

What battery manufacturer? That may be a restriction. Does each battery have an internal bms? Is each battery a 12v case? If connecting in parallel, you will need good bus bars or thick cables. I configured six, 24v batteries (8 cells each) into a bank of 48 cells (6P8S). Bus bar thickness...

SunRun installed a 9.2kW rooftop (7.6kW inverter) system for $42K. They will upsell name-brand battery banks for serious coin. I'm inclined to move kitchen, laundry and Home AC system breakers into a separate breaker box along with 100a breaker (half of the home 200a service). My goal would...

After typing in the command above, rasp accepted. I then typed 'shutdown now' and it rebooted and I am UP on v3.12! Thanks! I applied same to my primary SD card so both are now on v3.12. Success!

Is this the shell prompt?

I'm trying to use putty to access using SSH and when I key in the IP address and click on 'Open', putty shuts off. Is there a setting I need to update in Putty so it accesses the raspberry pi?

I've restarted Venus OS from the orig SD card and have confirmed I can access using VRM on my chromebook. From the firmware menu, I have booted from v2.91 and voila! I now have monitor enabled. I will study up on the directions to fix the monitor setting from your responses above. Thanks!

My problem may be the connection to the monitor on the raspberry pi 4. When I access VRM on my chromebook, I can access the Raspberry PI (including screenshot). I will try to disconnect and reconnect the monitor.

I've now performed the update using VRM. Frim VRM on my chromebook, I have confirmed the venus firmware updated to 3.12. However, the raspberry pi is behaving like it did after I upgraded using the other SD card. It starts up and victron energy blue screen displays and the...

You are correct. I did the Venus firmware update on the raspberry pi 4 while on the device using a bluetooth keyboard and mouse to navigate using GUImode on the device. I see the option to perform the firmware upgrade from VRM on my chrome book.

I'm using the Raspberry pi with the backup Venus OS SD card with v2.90. I can see this option above displayed when I select 'Device List' from the remote monitor on my Chromebook. Is this a safer option to upgrade firmware on a Raspberry pi running Venus OS?

I actually did it from the device itself. I have a bluetooth keyboard and mouse and used the keyboard arrow keys to navigate the VRM interface that the raspberry pi running Venus OS displays on the monitor attached to it.

Yes. Sorry, v 3.12. I tried the upgrade using VRM interface. When it rebooted, VRM didn't startup. Just got the Victron blue screen and the 'Last login:' message and root@raspberrypi4:~#. below that. When I replaced with my backup SD, it displayed this and then the screen switched to the...

I am using an Aims 6000w 120/240 inverter/charger. It isn't 'Smart' but is stone cold reliable. ATS works great and no issues in the 2 years I have owned. I have 1500watts solar and if I get a few days of clouds and batteries get drained, it does a great job of 'refilling' off the grid and...
