Planning a 2 x 3kW Vicron System
oddysee posted a topic in Inverters,
Greetings all! It's been a long time since I've been lured out of the shadows into signing up on a new forum. What a great place this is - hats off to all the community leaders!
While I'm new to solar energy, I'm a long time petrol generator user. In my previous city, it was commonplace to use a generator when the grid choked. In the land of wine and fynbos, however, I hear no generators and I'm loathe to disturb the peace - not to mention that I no longer have a dedicated generator circuit. So, I've decided to part ways with my Honda 6.5kVA genny to pave the way for some Vicron goodness. Things appear to be worse than they've ever been so going green and sustainable seems inevitable.
Until recently, I decided I would "settle" with Goodwe due to the integrated MPPT charge controller, cost saving and NRS approval. My first love was always a Victron though and I'm leaning more towards this brand once more. I'm particularly sold on the rave reviews, flexibility and their app. The VictronConnect app has to be the best there is! I'm an IoT guy and this sorta thing is super important to me. I don't only want to consult a small LCD screen on the wall or do battle with an app that doesn't update properly.
My casual obsession and nightly research has led me to plan a system around the Victron MP II 48/3000. While I'd love to spring for the 48/5000, it's not possible right now. In order to get a "foot in the door", I figured I'd start with the 3kW now and then add another 6 months later. Good or bad idea?
In terms of solar panels, I'm not really sold on anything right now. Battery-wise, I started off being 100% sold on PylonTech US2000B but I'm now intrigued by the UFO 5kWh. I don't have a ton of garage floor space but have some great wall space that is already next to a mini-DB.
Fire away, gents!-

Goodwe vs others
markus_m2 posted a topic in Inverters,
Hey guys,
Been doing a lot of reading here - some brilliant advice and posts.
I'm looking at installing a hybrid system - around 4.5kW Inverter, 3.6kWp PV and probably 2 Pylontech 3000s, largely DIY.
So here's the question - what brand inverter?
Leaning towards the Goodwe as a brilliant little all-rounder. Seems to include all function we require in one unit, good quality, easy install, and all at a pretty reasonable price.
But what would we be missing out on compared to the competition?
Thinking specifically Victron and/or SMA - what extra features and enhancements do these offer over the Goodwe? I hear the Goodwe is a little limited in the setup / programming one can do - this'd be a serious drawback for me. Are the others worth the extra expense and complexity? (As I understand both these other systems one would need seperate modular units as opposed to Goodwe all-in-one)
Would really appreciate your guys' reasons for preferring one over the other...-

I have one buyer who wants the who set up, but if they only take the inverter then I'll let you know -

Hi Thanks for feedback, makes sense, I have already suggested to client to increase battery setup. From what i understand the dyness has a 3.2kw storage, it can only discharge at 1,68kw Next question would of been what happens to excess solar power if load is minimal, but think you have already answered that, the mecer (mppt) limits or "throttles" it, is that correct? How does the Mecer rate compared to other invereters especially when it comes to switching, (from utility to solar, or vice versa, utilising battery when solar is not sufficient and so forth. Thanks -
Sealed batteries can recombine the hydrogen into water, as long as you don't boil them (in which case the pressure valves open and you hear that whistling sound). I also would not say I am an expert with lead acid... certainly less so these days. I'm working from the knowledge that Storage Mode in the Victron inverter/charger goes down to 13.2V per 12V increment, and their documentation states that this is below gassing voltage, but does not fully prevent self-discharge and therefore the charger will do an absorption cycle every few days. So what I can tell you is 13.5V is a "slow" gassing voltage and 13.2V is not. But as Coulomb points out, its temperature dependent too. -
