The unmarked units are intriguing to me as I am not going to grid - tie them However, you would think they would be marked down a bit more than the pre-order marked units... :unsure:

Does the spec label help?

Just opened everything up and here's a breakdown. Definitely NOS as they came in original unopened packaging. Not rust on the threaded rod. Looks like same anti-seize product I've used on spark plugs before. Fuse rests on the ABS with posts embedded into the mold it appear, they do not unscrew...

Been saving this in my cart for when my PV build was more immanent (which it is now) and right now on Amazon there is a $13 off coupon and 10% off promo. Dropped the brand new price down $20+ KAIWEETS HT208D Inrush Clamp Meter

Wow, that looks like a remarkable find. They're recommending leaving them in their module (which I am inclined to agree with) so would these work to use them in a 48v setting without removing a few cells? EDIT: I'm watching a video from David Poz breaking down this unit to work within a 48v system

Thanks hwy17 that's what I figured.

Amazingly helpful! Thanks so much Zwy ?

Oh, I think I totally misunderstood and derailed this thread, so mods please feel free to delete all of my posts. The allowance is only available for PGE charges related to service increase -- NOT -- an allowance for charges by an electrician for swapping out the panel and service lines in the...

Mine just arrived un under 2 weeks. Impressive. Now to begin wiring them up!

Super helpful info! Thanks so much ? I'm really debating between these cells and some Grade B 305ah cells on 18650 Battery

They are set to arrive today. I will keep everyone posted on condition

I'm about to place an order for the initial supplies to build my first DIY batter bank. My goal is to build two banks of 16s 48v packs to hit a goal of ~29kWh (connected to (2) LV6548s (32) Envision Grade B 305ah Cells (2) JK-BMS 200A Continuous/350a Peak - 2A active balancing Zketech EBC-A40L...

What is the reference for this rule? This is all I'm trying to find out is where this information is communicated. Nothing I received in my permit app has any reference to PG&E at all. I'm not trying to get out of anything. I'm trying to figure out how to best setup and implement my system...

I would but the Grade As are a bit cost prohibitive for me. I don't mind a challenge, unless it really is a ton more difficult. "Charge it up with the inverter, and dump the power to the grid or water heater." I have gas water heater and these will not be grid tied.

Just got back into town after being away for a couple of days and my batteries arrived! Can't wait to pull them out and wire up a series!

Just watched Will's video on this battery and although it's pricier per kWh than a DIY build the footprint and ability to place it outdoors is REALLY tempting especially in a smaller home where space is already limited.

I'm going to luck out and be able to install my (10) 400w panels in a single series along my carport/garage roof. It's the max sunlight/day and can drop right through the roof to my (2) LV6548's and future battery bank. Probably a dumb question as a beginner but since I'm installing in a...

I'm not sure if this is being posted in the correct forum so if mods need to move it I apologize. I am in process of installing (3) EG4 mini-splits (1 12kBTU and 2 9kBTU) to eventually be run by my PV system. For now, we have no HVAC in our house so this will solve that particular issue. I went...

+1 :cautious: same here I suppose. It's the freaking delivery charges that are killing us. We'll use only like $80 in generation and pay $130 in delivery.

Sorry, I'm a bit confused about the red flag -- what do you mean? As far as I have researched this is a reputable supplier of batteries which is why I didn't have any reason to doubt their statement describing the condition and sorting of the cells. There are reviewers of these Grade B cells...

Oh yeah, sorry. Each one is reated for 6500w. I thought that in series panels multiply watts and not amps. Ohhhhhhh voltage adds together so I'd be looking at 480v. Crap. So either I connect two sets of 5 panels in series to each LV6548 or parallel the two arrays, correct? Can I achieve 240v...

Found the discrepancy! After reviewing a month's worth of kWh usage from the mini splits in the house we are just now going to hit 40kwh which even on the most expensive rate from PGE would only be $25. Certainly not the $270 increase I'm seeing. After going through our previous month's data I...

If I am understanding you correctly the 250v max is per port on the inverter?

Oh for sure, I was just throwing out a quick reply to the comment. I am exploring configurations to avoid going anywhere near limit of the inverters.

I pulled a quote I received from a local solar provider when I was looking to squeeze into NEMA 2.0 back in January. Here's what they calculated based on my PG&E usage: 3.60 kWp (DC) w/ 9 400w Panels 5,748 kWh Annual Usage 5,419 kWh Production Yr. 1 (estimated)

Hi Everyone -- first post on the forum after many hours of researching, watching videos about off-grid setups, and combing the internet for deals to make our solar dreams a reality on a limited budget. I'm new to the solar world and was able to snag some QCells 480w 48v panels for $50/piece in...

Per the distributor: "Capacity tested, sorted, and matched for consistent performance." How does this differ from the same for Grade A purchases?

I believe it was around $3500 for everything. Parts were minimal as he was able to reuse the conduit up to the pull but he ran 2 new ground rods and all new ground wire, 200a panel. It was actually the most affordable quote I got, dude did a really clean job on it too.

Quick update: the shelving unit is pretty sweet. Very stable and each wire shelf is screwed down into the corners by a washer/bolt/nut combo. with those secured down it keeps the supports from popping loose out of the slotted receivers. I laid a sheet of 1/4 hardiebacker on top of each wire...
