I could be very wrong I’d think preventing any expansion in a completely rigid fixture would cause venting and or fire IF the cell experienced more expansion than what would occur from a normal full charge. Also if the cell was discharged with to many amps or simply abused then more than normal...

Awesome! Can the loads on these circuits be powered by the inverter when the inverter is operating in grid tie zero export/self consumption mode? Or are those circuits only powered offgrid

Very pleased to hear your working on the zero export/self consumption. The inverters I currently use always allow the grid to supply 7-25w. This (and slightly more) is acceptable imo. Short duration backfeed/overshooting afaik is unavoidable when using the inverter like a grid tie zero export...

if you use solar panels the inverters built in mppt will be utilized so no you can’t connect batteries and solar panels to the inverter input at the same time. One or the other

I agree a battery should be balanced prior to using it to power any inverter. The GTIL2 automatically starts to gradually lower its output as the total battery voltage gets closer and closer to the inverters total battery LVD. This is to prevent cutting off DC abruptly under high load. So if...

For most a power outage is very rare and only for a short duration. During the rare short duration outage, most would be fine with only the essentials powered by solar/storage, which doesn’t take much of an offgrid oinverter to accomplish that. Or a small generator unless the fuel isn’t...

I’m with ya.. having a setup that’s used like an offgrid setup when there’s a grid connection is pointless unless an agreement with utility can’t be achieved. There’s no reason to be harder on the inverters or batteries.

There needs to be an option from them with ALL the capability of this inverter without the built in chargecontroller..

An honest definition of off grid is not being debated. I never considered myself offgrid, to the contrary I use grid tie zero export inverters. that’s the entire premise of my comments.

That is only possible if the offgrid inverter is capable of powering the entire house 24/7. If you followed the conversation and didn’t cherry pic certain things than you would understand how that’s irrelevant. ?For most homes in the USA that requires a very large expensive offgrid inverter and...

I use GTIL2 inverters (grid tie zero export) that utilize battery voltage 45-90v. My offgrid inverter uses up to 72v. Chargecontroller is an Outback which charges to like 70 ish volts I think

I only have the essential loads offgrid. That’s all most people will need rare power outages or to survive when/if SHTF.. yes I have complete autonomy for those loads. 24/7/365 my all electric homes power usage is covered with grid tie zero export, except some days in the summer which can be...

Unfortunately this is a hard issue to grasp without having a grid tie zero export setup. there is differences. I explained them in the last few posts. offgrid would only allow for a smaller amount of loads as I explained above. the main panel however can be looked at as having a free 200amp...

But it’s far from the same as I tried to explain. Offgrid inverters require the loads to be moved to after the inverter. If the offgrid setup was only 4kw then all of the homes loads couldn’t be moved to after the inverter unless the offgrid inverter had a 200amp pass thru. Then if all the homes...

I use GTIL2 inverters. I got them many years ago before true hybrids (grid tie zero export hybrids) were readily available

This isn’t the thread for this so I will try to keep it short. my inverters were $300 each. i have 2 of them so $600 my panels were 30 cents a watt so right at $2k for 5.7kw solar 17kwh Lifepo4 batteries $2500 charge controller $500 offgrid inverter $500 thats $6400 thats zeroes out my electric...

disagree, we have had this conversation a few times.. there is zero export with a Ct on each mains. This allows the user to get the most out of the sun/solar panels. Also allows for a much smaller much cheaper system that only has to cover high constant loads rather than being sized for...

I know it a long ways off, but I’d like to recommend keeping the max Battery voltage at 65v. Victron, Schneider, Outback all have max battery voltages right around that amount. SolArk/deye however does not. i already have a charge controller same as most do. I like having that separate. I...

Awesome thanks for the clarification.

I didn’t gather that from Bob and Ryans post. From what I read the Rosie does not have the ability to operate like a “grid tie“ inverter. It can only supply power out of its AC output to a sub panel. Not to the main panel like a grid tie inverter would operate. However it does have grid support...

So yes, from what has been said here, the Rosie will continue to run at 7kw (it’s max output) and also have the grid simultaneously supply loads (on the AC output) that are above 7kw. This is a great feature. This is similar to what I do with my inverters but I do this in the main panel without...

Will swap it

I’m not sure what you mean. But if the grid was to support the load simultaneously to the inverters output but only below a certain SOC that would be a way that many would use it. So that the grid could assist the load when the battery was low.. yes programing the inverter to use the grid...

I guess he might have meant to say that if you set grid support to 70% the grid will then fully power the loads when the battery SOC falls to 69%. When the battery is above 70% SOC and the the inverter is in grid support mode the inverter can supply up to 7kw output and the grid can...

Unless “during this time” is referring to when the SOC is above that settable grid support percentage

“Rosie ignores grid until the ““Battery falls to 69%” ignoring the grid to me means it cannot help the loads on the AC output until the loads are below that settable percentage

The way I read what @Halfcrazy said was that the grid simultaneously powers the load when battery SOC is below the settable percentage not above.

yes that’s what I think he meant, however there could be a max grid support percentage. Also if the grid support is set to 100% what if the battery is at 100% and the loads raise to 10kw. Will the inverter shutoff because the battery didnt fall to 99% to enable grid support?

Yes 70% SOC is how i also read it. My question is what if that percent was set to 100%. Would the grid then (simultaneously with the inverter) always support loads above Rosies max 6-7kw output while Rosie continues to supply at max capacity.. if it can then all the homes loads can be moved to...

So the Rosie will not allow the rest to come from the grid simultaneously unless the battery capacity falls below the settable grid support percentage?

what if grid support was set to 100% Instead of 70%? Will the Rosie then never shutdown due to overload and simply allow the grid to simultaneously power loads on the AC output that are above the Rosie’s max output? While the Rosie keeps supplying its 7kw?

A few questions if you have a moment. If simply overloaded from constant usage over 6kw will the Rosie shutdown? Can the Rosie use the AC input instead as an output to the main panel for exporting to the grid? I see the manual says there’s ports for external CT. Would the main purpose of...

if all those above were slightly contained I’d assume it would be a lot more dramatic and with constant fresh air being pumped into the containment

From what I seen of lithium cells being punctured there is an explosion and I’d assume more so in a contained space. The containment was the door sealed shut. Not 100% sealed but contained more so then being out in the open. Then it blew open from pressure then the air then the flames.
