so why would I buy one EG4 18KPV @$5600 vs buying four of the EG4 6000XP for about the same price?

found this on Amazon... anyone know anything about them. ExpertPower 48V 100Ah

I am running 12 each 12v 200ah agms wired for 48v 600ah. 2 of them just melted... I want to replace the bank with lifepo4... what would be the best replacement, I'm thinking 4 rack mount type batteries. Cost is the biggest factor

I have 2 negative buss bars. The first one is between the battery bank and the shunt. The second one is between the shunt and my 3 growatt spf5000es. Should the negative from my fm60 cc go to buss 1 or buss 2? The goal is to get the shunt to "see" the fm60

New ground mount almost done. 3 strings of 8s, going to 3 growatt spf 5000. Top row will be 3s4p renogy 255 panels going to an outback FM60.

If using a breaker as a battery disconnect, and I have let's say a 400ah battery, then wouldn't i need a breaker rated for 400A? Let's look at the EG4 as an example... you have 4 batteries ea with a 100a breaker, BUT if you use a Nader 250a breaker as a disconnect, then wouldn't it trip before...

I have 3 Growatt spf5000es, I was using an old tablet and solar assistant as a display (mounted next to the inverters). My screen is now nothing but "fuzz". Also the cb in my truck gets nothing but static sitting 20 feet away in my driveway. I found some Faraday tape on amazon and was thinking...

Found this on fb. Hope you got paid for it. Will selling batteries

Anyone hook a outback FM60 SCC to solar assistant, if so how?

Does anyone know if the comm boards need to be the same for multiple Growatt SPF 500 es in parallel? I have 2 units bought from S.S. with the "older" comm boards (FW version 040.05/041.05) and a newer one with (FW version 067.01/068.01) also at what FW version did it go to 22 amps.

I have 2 Growatt spf5000es in parallel. I installed a 3rd and now I get error code 15. The 3rd unit is the only one with ac in hooked up. I have disconnected the parallel cables and the current sharing cable. It works as a stand alone charger. When the cables are hooked up according to the...

Does anyone label their arrays, such as array 1, array 2...etc. if so what are you using for labels. All three of my inverters are labeled. So are all the Breakers, switches and fuses. Hell even my wires are labeled.

The first 2 unites DO NOT have AC in going to them, and are set to charge OSO ( Solar only). the third unit will have AC input and will be used for charging at night. My question is if they are all parallelled, can I set #3 to SBU while the other 2 are set to OSO, or do they all have to be the...

I have a spare 48v 15amp charger and receptacle and was going to hook it up to my agm battery bank. Any problems in doing this with 2 growatt spf5000es hook up at the same time. I do not have ac in hooked up to them.

where is SA getting the PV information from. Is it just from the loads being used from the (2) Growatt SPF 5000, or is it seeing total production. I have 8.4kw of solar. but the highest SA has ever seen is 3.4(ish) kw.

Wow a shunt really makes a difference in SOC vs just getting data from my inverter. the left side was 2 days ago, the right was yesterday (after the shunt was installed). same usage both days. Shout out to the person who suggested SA and the VE smart Shunt...you know who you are...

I have 2 growatt spf5000es in parallel, and Finally got SA hooked up, but is only sees one inverter. Do I need to connect both inverters to the pi via usb?

I have a couple of questions. 1: if I wire the ac output from the inverter to an ATS, and set the LBCO to 48V or so... when the batteries hit the set point (48V) would the Growatt 5000 SPF es (us) shut down ( assuming no AC input on the inverter, just solar and batteries) 2: would the...

i am adding a Victron smart shunt to my (AGM) battery bank. does this look correct?

I have a strange glitch... randomly thru out the day ( and night) my Growatt SPF es (2 of them) will switch to AC in, and then back to solar and or battery, for just a split second. The units are not showing any faults, but its enough to trip the lights and such. I am using 12 200AH AGM...

MS4024 (120v only)...SOLD MMP 250-30 with BMK and shunt...SOLD OUTBACK FM60 ( includes BTS)...SOLD OUTBACK FM60 ( includes BTS) all in working order make me an offer for all or part (shipping to US only). EDIT do not ask for a price on here, message me or email me.
