Hoping to get some direction here. I have a grid tied system I do not touch, and an off grid system conected to a switched neutral critical loads panel due to the ng bond created when running my MPP Solar LVX6048 off batteries. I am currently changing batteries from the main, and a battery...

I want to make sure I understand the correct wiring of 2 charge sources for one battery bank monitored by one shunt. My apologies for the crude drawing. Can someone let me know if this looks right. The battery charger is currently wired directly to the bus bars of the battery rack. There is no...

My off grid and grid tied systems are separate except for the AC input to the off grid system to change the batteries and pass through the current to a critical loads panel. The off grid system is basically a partial home UPS system I have 6 of the Signature Solar EG4-LL batteries in the 6 slot...

I wasn't sure where to post this so general discussion it is. I posted in another thread on the subject of unfavorable changes to net metering with my provider. A coop that I have no option to escape from. I am grandfathered until Feb 2028 on the current 1 to 1 net metering per billing cycle...

I have an MPP Solar LV6048 for sale that was purchased from watts247 in January 2022. It's had minimal use. I would prefer pickup or meeting within 30 miles of Little Elm Texas. Priced at $750 for quick sale. Reason for selling is it has been replaced by an MPP Solar LVX6048. A single LV6048...

I just swapped out my LV6048 for an LVX6048 because voltage would sag badly when my 2.5 ton heat pump turned on, even with a soft start. this would cause other things in the house that are on the same critical loads panel to shutoff (tv, pc etc ). Anyway, not the purpose of this question...

I have a grid tied system and a separate off grid system as house back up with no solar attached. I charge the batteries via AC. Batteries are 4 x EG4-LL rack mounted batteries with bus bars. The off grid system is an MPP Solar LV 6048 connected to a 10 circuit, neutral switched sub...

I only found one thread on mixing batteries. Just want to be sure what I am wanting to do would be ok before I drop the cash. I already have 4 x 48v 100ah EG4-LL LFP batteries with 6 slot rack. I have an opportunity to get a great deal on 2 x 48v 300ah Big Battery Kong Elite LFP batteries...

I've searched the threads, but can't find a discussion about my specific situation. I have an MPP Solar LV6048 and 4 x EG4-LL batteries (400ah/20.48kwh) . I am not charging with solar yet. Only charging with utility power currently. I have the AC input of the inverter hooked up to a dedicated...

Ok, building my storage system bit by bit. I can run most of my house off battery, but I am having a voltage drop issue. My apologies in advance for the long post. I want to provide as much info as possible. Here's the build. No PV connected yet. I use AC input on the inverter to charge the...

I didn't want to hijack this the thread ... https://diysolarforum.com/threads/pv-combiner-box-voltage-to-inverter.37892/ I have started my dive into battery backup. I am using the same MPP Solar LV6048 mentioned in the linked thread above. The batteries (4 x EG4-LL 48V) and inverter are setup...

I have purchased 3 EG4-LL batteries and the 6 slot rack from signature solar. This will leave me 3 open slots for expansion. which won't happen for some time. Maybe one battery a year. I want to mount the shunt and T Class fuse close to batteries/buss bars on the rack. Being a computer junky...

Ever since I cancelled my Bluetti order, I have been itching to put my own solar generator together. I have a 10.4 KW grid tied system already but want to put together something off grid as a general battery backup. An electrician has already installed a 10 circuit transfer switch along with...

I have cancelled my order for the 18kwh Bluetti AC300 & B330 with spilt phase fusion box set up i previously due to delivery dates being pushed off by 3 months and all the issues I am reading that user are having. This whole system was going to be hooked up to the 10 circuit manual transfer...

I know this is a diy site and my choices haven't been diy but the money is already spent and I need a solution that doesn't require a rip and replace. I'm ok with additions to get me where I need to be, but rip and replace is not and option. Sorry for the long post in advance. I have a 10.4KW...

I'm sure everyone on this forum watches the advancement of battery technology. I am really interested in the ECO FLOW Delta Pro once it's in general availability. I've watched a few of the review videos and am hoping to see one from Will in the future. I am a DIY'er to a certain extent, but...

New member here. I have searched the internet to try and get an answer to my question to no avail. My apologies if this is the wrong place to post this. I just had a 7.4kw system installed consisting of: 20 x REC 370 Alpha Black panels 20 x TS4-R-SMA optimizers 1 x SMA Sunny Boy 7.7...
