Sol Ark 15K updates and added a growatt inverter as charger only from alternate generator

- solark 15k wasn't really pleasing my thoughts on how it was powering the house, as everything is LED the lights would constantly pulse a little bit, very annoying, so I am using the growatt to charge instead of the generator that is currently hooked to sol ark. I am by no means an electrician or have any professional advice to give, at your own risk.
head to diysolarforum.com for more information and an OCEAN of knowledge. Thank you to the community for everything I have learned!
we have a chargeverter for this now! :)
Meh for the price I'd still take an inverter then I have a spare inverter in case. Although I like the eg4 inverter instead as it's already split phase and can charge at 120A!
You need to have a proper plug inlet to the Growatt inverter, as right now all of the cords would be an electrocution hazard if unplugged due to the live plug prongs.
This inverter is only active when the generator is powering it. Leave in standby mode. When the generator is off. Inverter shuts off and also turn off breaker to 48V. This type of charging needs to be monitored. It's not automatic. The auto charging is through the sol ark worse case scenario. It's no different than back feeding your breaker panel. Male to male.
@@mylesoffgrid Still no reason to not wire up a plug to the inverter charge input instead of a receptacle.
Yes you are correct I will look into this it's a simple modification! Thanks for the great feedback! Proper term for this setup is called a suicide cord. Beware that you should as mentioned never have an exposed male live cable.
"Double Conversion". Isolates your AC system and your generator from each other. I DIY'd mine with ~3kw of power supplies but have thought of buying an additional Growatt specifically for that purpose. The interest in this approach is huge, judging by all the hope and drama that flared up overnight about the EG4 Chargeverter. The funny thing is, if one is willing to use an AIO as ONLY a battery charger, there have been ~$500 options like that for at least a year or two, maybe longer. People act like a $400 100a charger is a new thing, but only because they do not consider the possibility of doing what you have done and using an AIO as JUST a battery charger. In that sense, while a Chargeverter is cheaper than a Growatt 5k, it is not MUCH cheaper than the $500 48v AIOs that have been available for a while now from PowMR, etc.
Exactly! Sometimes people just don't think outside the box like they used to, I like the fact that I have a "Spare" Inverter around in case the SHTF with the sol ark at any given point. I have a spare auto transformer lying around that I could put to use in a worse case scenario.
Started a new thread on diysolarforum to find a list of inverters with more charge capacity.
Cool set up man
Thanks!
That's not a bad idea, have the solark do the auto gen start/stop but use something else to charge with. Solark really should fix that, they have a full 60 seconds to modify the frequency slightly and then load up on the generator slowly to prevent the issue.
That might not help the issue because the sol ark uses common wire to charge and discharge, so you cannot have current flowing in two directions, sol ark will always use gen power to power the loads then the leftover gen power goes to charging.
Nice setup! Why not use a transfer switch to alternate generator inputs? Then the solark would see either on the input
I do not like way sol ark has to pass the gen power through to the loads. Makes all the led lights pulse and flicker even with a generator that has extremely low harmonic distortion. And a rock solid 60hz power only loading gen to half load. Still makes lights flicker and some of my hydronic relays bUZZ. this way with the growatt it's just charging works much cleaner!
Which Growatt is this?
Growatt 5000es
