Yeah. The problem with the sunny islands is if I'm connected to the grid, either exporting or charging the batteries, it will always pass the grid to the loads, and keep the battery fully charged

It would be replacing the sunny islands. I love the sunny islands but they are not set and forget- I have to change settings daily.

We'll have to see but it uses the same portal and the settings look very similar

Imo grid interactive inverters all have good hardware. Where they separate themselves is the software and the reason I'm about the growatt is I like their software.

Oh damn! I'm ready. So now the question is do I want to wait and see what signature solar will sell it for or do I just want to go ahead and pull the trigger. Tough one

I don't understand what you're trying to avoid here.

There are several available in the 10kw class. I didn't mention them because I wouldn't consider them

He said 50a at 240v

Many ways to skin this cat. Easiest: get a grid interactive battery backup inverter, eg eg4 18kpv $4900, solark 15k $7000. Or wait for the new growatt sph 10000tl for about $2600

Good point. The way my setup works right now is it stays at full battery until I disconnect the grid after sunset. The new hybrids are different so I'll have to develop a strategy for that. Thanks for pointing that out

May not hurt to email center point. My utility wasn't listed. I emailed them and they said they could do it. I use iotawatt for my main panel. I'll need to see if there are notifications. Today or tomorrow I'm moving the CTs for my growatt to my main disconnect so it can see all house import...

ok, that's a solution that I can use. thanks. My sunny island automatically does this. if an external charger is raising the voltage higher than the sunny island setting then the sunny island will export as needed to maintain the voltage. I just needed to know if other hybrids do this since I...

What I mean is , let's say for some reason I have pv attached to a victron charge controller that's feeding the battery. If the battery gets full will the solark transfer power from the battery into the grid so the soc /voltage doesn't continue to climb?

I use the cheap zigbee one that talks directly to the meter . Some utilities allow this. It's only about $40 Vue Smart Home Energy Monitor | Works only w/PG&E, SCE, PPL, First Energy, Ohio Edison, Burlington Electric & Green Mountain Power | Connects to Your Electric Meter | Solar Net Metering...

So I don't know where the other party got the idea you meant 80,000 kWh for the month 🤷🏻‍♂️🤪

I thought you meant you should be able to make 80kwh/day during december

That's very cool. Thanks.

with 1:1 net metering, having a battery will cost you money, not save you money. a good grid tie inverter will export 98% of the pv directly to AC. with a battery system, you save that to a battery at 98% efficiency ,if DC coupled with mppts, and then convert from battery to Ac at maybe 88-95%...

thanks for this information. the mppt charge controller is a standalone unit?

if you have grid export on a grid interactive inverter like solark 15k and eg4 18kpv, lets say there is separate mppt charge controller that's also charging the battery -, when the battery is full, will the inverter export from battery to grid to keep SOC or voltage from climbing too high?

Altestore has closed?

so like greentech renewables?

Read this. May take a while though https://www.pec.coop/wp-content/uploads/2023/11/Interconnected-Generation-Value-of-Solar-Study-Report-1.pdf

After the tax credit some of the new ones are not much more expensive and will last longer. Also higher wattage so lower mounting cost. You paid about .14/ watt and new ones after tax credit can be as low as .2/watt

I think I have more clarity now. I went back and read the main manual. It looks like it will only charge from grid if the battery is below the set soc, and will charge to the soc set in the battery % box. Very nice. So if I'm discharging and it gets to low soc, even if grid charge is...

I don't plan to charge from the grid but such a lack of control is not ideal.

I'll have to look into that. My sunny islands can automatically start charging the battery from grid if soc falls to a programmable level. And you can also set the soc where they stop charging

Ok that's good to know. Right but that's what's confusing. There doesn't be a way to set how much you want to charge from the grid. For example, if I wanted to charge from grid if soc fell to 10%, and I want it to stop charging when soc is 25% , how would one do that? I talked to growatt USA...

Yes! They were supposed to be available last month and here we are still waiting

You must have 1:1 net metering. I don't so the net number is completely useless to me. Matter of fact, that is one thing I absolutely hate about my zigbee emporia vue. It knows how much was imported and how much was exported, but it only shows me a net figure, which does not allow me to...

It's very confusing. If I don't enable grid charge, when soc drops to my setting, it should just stop pulling from battery and pull from grid. I don't understand what grid charge does exactly then if it's only maintaining the soc.

Looks like in on-grid mode the system doesn't Even use the battery unless the grid is down Looks like it powers home and backup loads from pv then grid

Thanks. 4.3 battery charge first mode is the least likely way I'll use this inverter though. The mode I'm likely going to use is 4.1 load first/self consumption, with pv sell. Typical Load First / Self-Consumption Mode Priority of Energy Sources = PV > Battery > Grid Priority of Energy Usage =...

Operating modes document. Only question I have is, under time of use, if grid or Gen charge is checked, it's starts charging from grid or gen but when does it stop?? When battery is full? When the soc or v has been met? Need clarification on this

So how's solar assistant vs the built in app?
