In cells that are getting mild bellies, what gas is being produced? Are the vents usually designed to do an as-needed release to keep the pressure under some spec pressure or are they one-time plugs that blow out? Are there generally obvious signs that the valves have released something? No...

I'm hoping to jump into some of the newly possible integration between devices. I am very confused about how all of this might fit together, I have: 2x Victron SmartSolar MPPT SCCs with VE.direct USB cables 1x Victron MultiPlus 24/3000/70 with a VE.Bus connection to a MK3-USB interface A...

This will power my home office on a daily basis and serve other needs during outages. Our part of town is ~70 years old and the power is still on poles. 70yo oaks and hung powerlines gets us 2 or 3 multi-day outages a year. Building it mostly out of parts on hand from other projects, so there...

@Will Prowse What do you think about an Automation subforum? Now that some people are discovering Node-Red integration with VenusOS and how that connects the entire IoT world including Alexa/Homeseer/etc to our DIY power systems, we need a place to discuss that. This is exciting stuff! Thoughts?

Does anyone have experience with automating the activation of the newer breed of wireless remote start FOBs? Examples are the remotes that come with the Westinghouse igen4500 and the Champion 100573. I'm looking for a way to trigger the remote start and stop of this kind of generator. I have...

I've had this for about a year and a half. It has served light duty during power outages. It is the stoutest piece of electronics that I have ever owned, but I just don't need it any longer. It has lots of integration and automation features. See the manual for details. Specifications are...

Does anyone know what RJ45 pins are used by VE.Bus spec? I have not been able to find this info.

If I have a panel, it's spec chart, a multimeter, and no real access to light, what tests can I do to determine that a panel is not dead or very seriously damaged?

Hey all - I use a rattle trap generator to keep my batteries topped up for quiet running overnight. It is low quality and responds pretty poorly to changing demand. When it's pushed beyond 50% rated load, it puts out terrible power and results in quirky appliance behavior. It killed my fridge...

Has anyone figured out the full logic that drives the 'on' and 'off' of the SBMS0 EXTIOx on this BMS? Specifically, I am interested in the Type 1 (HVD) and 2 (LVD) conditions. The other types seem straight forward. I dived into the source code, which seems well organized, but I was not able...

I have a Samlex EVO that is designed for generator AC input to charge batteries. I also have a 3500 watt run of the mill gas generator and a 2200 watt inverter generator. One of the EVO features is to set a maximum current draw for AC inputs, including the generator input. If I needed to run...

I was really intrigued by this device and the SBMS0 that goes with it and have a set the way. The SBMS0 BMS does some neat things that suit my needs, but I am not necessarily decided on the odd little solar charge controller module. Anyone have one or more of these? What do you think?

I have some 200ah 24v batteries that I'd like to put in parallel to increase capacity. How close in voltage do they need to be before I can connect them? Since the relationship between voltage and charge is so flat in LiFePO4 batteries, I guess I am concerned that a small difference in...

Is this line not available in the US? Seems like there would be a lot of interest. Has the appeal of the brand reputation for quality and the simplicity of an AIO. Anyone run across one?

Do these units have any issue taking AC input from MSW generators? Example: The mains are out and it has been cloudy for a couple of days, so my batteries are getting low. I can crank up Ole Smokey and plug in the AIO for a while to boost SOC? It looks like setting 11 'Max utility charging...
