Hi Folks, I've put together a backup battery power cart with 4 x 12V-200 amp Ampere Time LiFePo4 batteries. I have this converter/charger and I want to run my refrigerator, freezer and wifi network when I'm away for weeks or even months off the batteries, then have the converter/charger recharge...

Can anyone tell me if the EG4 6500 EX48 will allow me to use Solar first, Grid second and Batteries third? I need my batteries for grid down only. Thx

Hi Folks, I'm trying to connect my 2 parallel wired batteries today. Can I connect my 45Amp LiFePO4 Progressive Dynamics Converter / Charger to a 12 volt fuse panel first, then to one of the batteries? The charger/converter has under and over current protection, so I'm wondering if I also...

Hi Folks, I've just set up a power cart with 2 Ampere time 200 AH 12V Lithium batteries. It worked so nice when I had a power outage yesterday I've decided to run the gamut and want to buy 2 more batteries and panels and an all in one and run my house off the sun NOW!!! I want to buy 2 more of...

Has anyone had a bad experience with shopsolarkits.com? Are they in the USA?

Hi All, I have a EG4 3KW inverter that is fed by a 30 amp breaker from my main panel and also a 48 volt 200AH battery bank. It is feeding a critical load panel, with grid first, battery second and solar (yet to instal) 3rd. I did it this way as I'm not always present when we have an outage...

I haven't seen a lot of information on this here. I need to make up some new battery cables and have a bunch of 1/0 and 2 AWG aluminum wire left over from running a service entrance to my garage. The 1/0 is rated for like 200 amps, the 2 AWG 100 amps. Why shouldn't I use it. I've searched a...

The panels I want to buy come with them and I want to replace them with optimizers. They say the value is $30 each. What would someone offer for 22 modules?

Hi All, I'm making a portable battery cart, can I tie the charger/converter and the inverter chassis' to my negative buss? Or, am I better off just tying the 2 components together on the case grounds? I've seen this question posed many ways, just not an answer that will work for me. This is...

Hi, wondering if I'll need 2 strings of 4-12 Volt batteries to power these or can I just use bus bars and divide the power between them? I have 4 200 AH LiFePo4 batteries. Sorry about the bold, I copied and pasted and couldn't figure how to make it normal? 6kW 48V (2 x PIP3048LV-MK 3000TL) MPP...

Growatt 24V SPF 3000TL LVM or MPP HYBRID LV2424 – 24V 2.4kW Also, will I have any trouble setting up the charger in the software on either? The growatt says my BMS will not communicate with the inverter?

Good Morning, I have a EG4 3K setup with 10K 48V Batteries connected to the grid for a backup panel.. Works great. Original plan was to add another 3K to this one so I can run 240V also. I am ready to do that, but now I'm wondering if I would be better to replace my 3K with a 6000XP? (I have a...

Good Morning I' haven't had luck getting answers on my own, hoping someone can chime in and help. My choice is: used 1 year 365 watt monocrystalline solar panels, 72 cells, VOC 47.6 volts , ISC 9.9A for $140. each, Pallet= 30 panels OR New 280W Poly-crystalline Solar Panel, Wattage: 280W...

Hi Folks, My question is should I use the same + and - battery posts that I have wired my Inverter from or the opposite posts, or does it even matter? Same question for the inverter, does it matter if I connect the inverter to the + and - of the same battery or to one post from each battery? I...

Actually, I woke up and did the math again and apologize for writing this while I was still sleeping :)

Hi All, I have a beach cottage in the Bahamas that is tied to the grid and we have rolling blackouts, as well as unannounced outages weekly. Last time we had one I plugged in a 100 watt inverter to my car and had fans and lights for the 4 hours it was out. My battery started my car the next...

PowerMax PM3-55-LK > 55 Amp 12 Volt Converter / Charger Hi Guys, I could really use some help choosing here. I'm looking to buy something tonight that won't hurt my 200 AH 12 volt Ampere Time batteries. Can I leave this connected overnight or all day when I'm out...

Hi Folks, There seems to be so many solar savvy people on here, it's staggering. Lots of knowledge to comprehend. Hoping there's an easier answer than learning the whole Solar Handbook! I mentioned earlier I already purchased a Renogy 12 volt INVERTER which I can return if there's a better...

Hi, Would it be ok to exceed 500 volts for my EG4 3KW inverter that says 500 volts max, if I put 2 panels that are 52.9 voc., on each of 5 sides of my Octagon roof? I'll be way under the 5,000 watt rating (390 W each), and my thought is when the panels that face East are getting full sun, the...

I finally have my panels! I want to utilize 4 series strings of 5 panels each facing different directions, and there's only 2 MPPT inputs on the 6000XP. My cottage is an Octagon How can I do this? Do I need to buy more MPPT's, to keep them from bringing the power down on the other strings...

Hi All, Thanks for all of the answers sent my way, I do really appreciate it. I have another question. I bought 2x 200 ah LiFePO4 batteries with 100A BMS's. Can I wire in parallel and send double the amps to them from the charger. In other words, I was told I shouldn't exceed 40-50 amps per. Can...

I just purchased a Victron smart shunt (as many have suggested), and want to monitor and hopefully control my system over the internet from home 1200 miles away. I don't want to keep buying the wrong things as I've read so much about different ways of doing this. Very soon upgrading to a larger...

What, if anything, do I need for an Over current protection device between my Buss bar and this unit? I have a 125 amp breaker between battery+ and the buss bar. I have 4 x 12 volt 200 AH batteries in series that all have 100 amp BMS's. They feed a EG4 3000 EHV-48 solar inverter charger. No PV...
