That's not true. Did you know Abrams tanks are currently powered by jet engines? Certain vehicles such as the Abrams, Booker, Stryker, and possibly some others are going diesel/electric hybrid, where the diesel exists only to re-charge batteries. Being able to operate for multiple hours of...

Why do locomotives run diesel/electric setups without mechanically linking the engine to the drive wheels if that is always more efficient?

I believe this is the problem some companies are trying to solve with smart home management panels and load control panels.

Unfortunately, that's not an answer I'm equipped to give simply because I don't know (not a function of what I do). Also, there's a ton of factors considering roof size/ complexity and your solar system size/layout. They're expensive, so whatever you think it costs, double that number :P These...

Hell yes! The "air-boat?" concept could work out very well if the motor spins fast enough to generate decent thrust from a propeller. No wheels required, just skids.

Good to know. Probably a dumb question, what is the significance of the 160A?

Hopefully the grids are prepared!

More sources of power generation (and storage) are a benefit to society as we move to the decentralization of everything. No one will shed a tear for the power companies making less profit.

Well then, that certainly makes it simple. Thanks much!

True, I hadn't considered that. Added cost probably isn't worth the tiny amount of convenience you'd get out if it.

Any updates on this? Could really use a bunch of these as we are doing a project intending to use 60kwh of EG4-LL's and the 6 slot racks are about a foot too tall.

Hello all, first post as a new member, longtime lurker. Does anyone know of a solution for reducing the size of a PV string (in series) using an AC-coil power contactor/relay? A part number would be fantastic. The objective is to isolate a string of panels down to just three panels to charge...

One of the snippets above has some incorrect information. GAF Timberline Solar Shingles are not rack mounted, they're direct to deck. My company installs them on a regular basis, along with many of the other Solar Roofing systems mentioned above. They're very attractive systems aesthetically...

Weight reduction and/or fiddling with gearing might be your only avenue given the aforementioned restrictions.

Hi, I am designing a project (not my own) and looking for some guidance. Homeowner has a 400A service that is split into two 200A panels off the meter. Homeowner wants a Sol-Ark 15k with 12x EG4-LL batteries for backup (2 stacks). Customer does not wish to add a PLP or do any load management...

I believe what you are looking for is in the manual. Page 53 https://www.sol-ark.com/wp-content/uploads/15K-2P_Manual.pdf <-link

Thanks, after multiple discussions we are now planning for dual inverters.

This is what we do. Use military compass and adjust for magnetic declination based on location to get true south. After a bit of testing, we found the phone apps aren't very reliable.

Bump. Has anyone ever figured out how to capture "total production" from a Sol-Ark (or EG4) inverter, not just the exported energy to the grid?

The intent here is to use transfer switch in the event of grid failure to power main panel through the load side of the Sol-Ark 12k from battery/PV... normal grid-tied operation otherwise. Homeowner is aware they will have to manually shed loads in the main panel before activating bypass...

SolarEdge has a 5G cell card that is pretty much plug and play for communication instead of Wi-Fi. Pretty simple to install and configure in SetApp.

The "Solar PV" value should be correct if the CT's are revenue grade. Would be nice if there was a way to display it in a monthly value instead of daily without having to do math manually. Correct me if I'm mistaken: the value for SREC reporting would be ((Load Consumption + Exported to Grid) -...

So Understood, that's how it works with pretty much all grid tied inverters, a pair of CT's capture the values as they exit the inverter through the AC connections. With hybrid setups, there's PV produced power that can go out of the grid connection AND the load connections. Wouldn't that...

Agreed.
