You can set the maximum charge rate from utilities to 2amps in settings 11. That will not charge much from your utility and when the sun gose back up it will charge full speed.
@@zepeda2820 yes, some settings can be set via solar assistant. Not everything but the inverter set, ie solar battery utility can be adjusted. not a ton of control
Yes, possible, but I choose not to. This way i control all my hardware. If you grid tie, you have to have a professional installer do it all which costs thousands more.
Why are you using the grid to charge your batteries at all if your goal is to the "maximize savings"? I have a Growatt 3000 and use the OSO solar only setting and only charge the batteries from solar. In addition, the LifePower4 batteries allow me to set the "back to grid" setting as low as 5% (although I use 15%). Then I set the "back to battery" to 25% since the sun is charging strong by that point.
I have 3 kids, we need power even when the sun doesn't shine, so the sun supplies what it can when its out, otherwise we do still need to use the grid. I wish i could turn everything off when the sun goes down but with a family, concessions are made :)
@@MicahGallant I'm getting my units within the next week, and I will be setting mine up very similar to yours. I think if you set Program 1 to SbU, it will use solar to feed the output circuit, then battery, then utility. That way, you can change program 16 to be OSO (Only Solar) to just charge with solar. You could also set program 11 to be 2A and charge it very slowly, so solar kicks in and picks up the rest. Great video - thanks for making it!
@@daviduhl7444Good stuff, enjoy the process of getting them configured. Yes, I think there are may ways to optimize usage, it really depends on your needs, how you have them installed and what you're doing with them. For example, you can turn on the energy saving mode to shutdown the inverters but for my application, its not usable as there is always small loads on it as I power my whole house.
Does anyone know how to configure EG4 3000EHV to operate like an online double conversion UPS and solar is contributing to utility charging? I want batteries to stay charged at all times to maintain load uptime in event of utility failure and not maximum return on investment from energy savings. I only want load on grid if the batteries or solar panels are being serviced. I want the load isolated from dirty utility power that causes my home electronics to have to be rebooted more often on grid power,
You can set your min and max limits for power, so set min to 70% charge, max to 100% and you will be assured of at least 70% power when the grid goes down. its an option on the screen for it. Works well. Mine is set to 20% and 60% so that grid stops charging as soon as possible to wait for the s un
I don't understand correctly what you are saying or what you are meaning . If you are filling up your batteries with solar power - why do you charge from utility up to 60 % before the sun shines ? I kept hearing you say that to maximize solar collection - you charge the batter with utility to 60 % ? ? ? At first I thought that you were logically saying - to maximize solar collection - you discharge the batteries to minimum . Why wouldn't you discharge the batteries to minimum just before the sun shines ? If your use utility to charge them to 60 % then you only have 40 % capacity left . If you discharge to 10 % - then you will have 90 % capacity to fill .
So what i do is limit the grid charging of them, they only ever are charged to 60%. That way they never get full in the day or less chance. There will always be room in the batter to store more during the day by NOT charging them with the grid to 100%. I still need grid as my battery is small so i charge it the least amount i can so when the sun does come out, there is lots of battery to absorb it
@@MicahGallant I don't see any reason to charge the battery from the grid . You are getting energy losses when you do that . If your goal is to get more energy from the sun - then have the battery discharged as much as possible before the sun shines . You should get more current to the battery because it is at a lower voltage . Then after the sun goes down - just use what the battery has - then after the battery discharges - it will automatically switch to grid power . Do you have your system set to automatically go to grid power when the battery is depleted ? I think doing it this way you may find that you get a little bit more solar energy collected . And you will not be spending money charging the battery unnecessarily . It cost money to charge the battery and then more money to discharge the battery . I say it cost money - really means losses of power - however - if you are ever needing to use power from the grid - then it is costing money .

Yes thanks, indeed I have it set to 15 amps right now. Good idea on that!
Are you able to change the settings on the eg4 3000 via soler assistant remotely? I know you can on the eg4 6500 but not sure on the eg4 3000?

Can you change the inverter settings remotely in solar assistant on the eg4 3000? Or is it only in person?
Remotely it work with dc home app
How many panels do you have and what wattage?
running just under 3kw total of panels in a couple of arrays. not much. Its a start.

Can you provide any information on the raspberry pi your using?
Its the Pi 4 from Solar Assistant, purchased right from their site: solar-assistant.io
you can take the battery as low as 3% I have this same battery and inverter
how did you bypass the build in eg4 limit of 20% lower limit? In speaking with Sig Solar, the battery doesn't let you use lower than 20% if I recall
@MicahGallant there is a setting on the inverter to go down to 3 percent
