Well it is official! I received my long awaited 6.9Kwh masons today from Seplos! Looks like we are going to be getting our orders. On first look the batteries are brand spanking new with all matching voltages.

This is interesting....I have never thought about doing this.... Found a Solaredge document which outlines a way to do this without a solaredge inverter? https://gridalternatives.org/sites/default/files/se_power_optimizers_installation_guide.pdf

EMUSBMS Centralized will do that. It's pricey, but it will handle the communication and master disconnect / charge for a large parallel pack etc. Another Boot ass way of doing it would be to place multiple BMS's that have a disconnect feature and just string them all together IE in series so...

I am in a very conflicted dilemma. So I have both of these inverters and can proceed with either one? BUT I am torn as the best approach for my system, which can change like the river flows down hill. I own a Sunverge Cabinet, it has a SE XW+6848, a Sun verge control etc. and KOKAM 11.6kwh...

Thanks for the input! I am a little worried about the control aspect of the SMA units. I think the battery integration will be pretty straight forward. But the Feed-in and trying to do any load shifting or power output is a little clunky with the SMA Units. We shall see! I am getting ready...

Hi All! I recently obtained a overstock of some Ironridge conduit mounts and magnum 100amp panel breakers. Not looking at making money on these just want them gone to our DIY community. The Ironridge conduit is the FM-CM-001-B Conduit Mount Kit in Black with 4 mounts per box. They secures...

Yes I got the same date for eta in the US. Got a reply to my email this morning.

Funny - I found my answer in another manufactures documentation! What a pain! Still curious what people are doing in the on-grid vs off grid panel connections when connected at the same time? AC System Bonding Multiple AC Neutral-to-Ground Bonds: Verify that only one neutral-to-ground bond...

Mike - There is a guy on Ebay that does the repair of the SE inverters. He fixed the mosfets and diodes for me on my inverter. This is the service... https://www.ebay.com/itm/403449719417?hash=item5def7a2a79:g:NQIAAOSwIaJhnchN He has other items for sale and does the work. Get the...

As stated above get a hybrid water heater, I cannot speak highly enough about getting one. The unit I bought puts out cold dehumified air year round. The garage is where I specify them in the houses I design. Also consider an induction stove top, they heat very fast and the electric coils of...

Cool! I was actually thinking of buying one of those as well. I do wonder how they would handle shutdown etc without the key turning off the SafeDC function? Very interested in having you unlock some for me, but need to find a way to handle rapid shutdown since it will be on my roof...

The gateway gen "one" uses rs485 battery to inverter. The disconnect switch is just a 12v actuated relay. I have some photos of the guts' if your interested in the gen one units. The nerurio is only compatible with tesla systems not online. The "brains" are in the gateway.

Correct? In looking at this is only Europe and seems to have only been allowed with the IOP P401Ii optimizers? I would be curious if this would functionally work on some of the older Opto's coming off market with all the upgrades happening.

HI All! Well getting ready to do the final permanent install for my XW+ in a grid tied inverter with AC coupling. I have been pouring over the documentation for wiring diagrams but the neutrals have been perplexing me? I have including a wiring diagram for reference. The XW+ units are...

No I have not received my units yet as well. I am starting to get worried, but in emailing with Adam seems like my FedEx tracking order is legit? He mentioned a week or so ago that the container would be in the US soon but yet we are still waiting. One more email back and then I think its a...

Well time to clean out some old projects - All located in Newcastle California - prefer local pickup if possible. This is almost 10kwh worth of cells :). I have 48 medical ventilator battery packs that are Philips 14.4v packs each holds 20 Sanyo white top li-ion 2200mah cells. Each pack is...

Ok so I have this new install question for at my house so if any of you electricians or solar installers could help ? I have a grid tied solar edge feeding main panel. I want to install a new SE XW+ 6848 as backup and grid tie. The problem is I do not want, nor would I have a need for a...

Thanks, Sadly yes I had to install a new all in one MSE so I am stuck with finding a method to pull the panel off grid. Most shunt trips are 110v so just thinking that I could put it on the Load side of the SE and it would actually power the disconnect? But yes one small error and it would fry...

Where are you and what do you need? I design here in the peoples republic... so its IRC 2018... But I know the older stuff as well.

Yes I ordered two of the mason units. I have a tracking number that will be 6 boxes when shipped (Seems about right) total 172#. The FedEx tracking number is referencing some Huin-Ocean invoice number and has a reference number that I believe is my order number. The location of origin is...
