Wanted to buy EG4 48V Waterproof 5.12 kWh Batteries

Yes. The LVX6048 has a N-G bond controlled by an internal relay. The relay is normally closed (N-G bong created) and open only when power is applied to the Grid/Generator 240VAC input to the LVX6048. Thus, when operating only off the DC input from Solar or Batteries there is an internal N-G...

Measure the current on the ground between the LVX and the Panel

I can confirm this is the case in Battery & Solar input mode. The issue is if you backfeed into a main panel via a backup generator plug 30 amp breaker you will create a N-G loop and your GFI breakers will trip. Typically gas generators do not have a N-G bond. A N-G bond somewhere in the system...

MPP LVX6048: Are the Neutral and Ground bonded inside when using only battery input? If this is true when back feeding a main panel there will be a ground loop when between the main panel (N-G bonded) and the LVX6048 ( N-G bonded). Can it be confirmed that the LVX6048 operation is identical to...

Inverter to BMS communication using % charge has many advantages over just voltage settings.

Small Honda inverter generator. New 3600 fuel injection model is out. Paired with a EG4 25a 120VAC to 48VDC battery charger to keep the batteries charged.

Yes. And does have a transformer https://www.mppsolar.com/v3/lvx6048/

The current MPP LVX6048 allows up to 430VDC into the PV input but is limited to 22 amps. The new MPP LVX6048WP has two PV input up to 600VDC with 15 amps each but limited to 7.5kW. They can be used in multiple strings for more power output. It has 120/240 VAC input capability and output. And...

The MPP LVX6048 does not specifically list the EG4 LiFePO4 as supporting communication with the battery(s). Looking for evidence it works either automatically or can be set up manually. Compared to GroWatts that only require a menu setting then plug-n-play.

See Will’s post and follow the thread: Thread 'Safety hazard w/ Growatt 5000ES (European version) when connected to American grid' https://diysolarforum.com/threads/safety-hazard-w-growatt-5000es-european-version-when-connected-to-american-grid.33975/

Have you confirmed that the 5000es that you purchased from someone other than Signature Solar (SS) have the Neutral to Ground screw removed on the PCB? The 5000es from SS are modified by GroWatt at the factory by removing this Neutral to Ground screw. Reading multiple threads it appears that...

It’s limited by the DC output not the PV input. It’s actually lower than 6000W as the DC charging output is limited to 100A x VDC for your battery bank type bulk charge voltage.

Read through this forum for grounding issues to take into consideration with the mid-point transformer.

With 10 in series (416VDCoc, 17.3 Impp) you’ll be on the edge of the 5000es PV input both VDCoc and Impp with no margin for cold sunny days. That said, I see no issue.

That picture is a Fusion for the EP500Pro not the AC300. They are different based on the plugs being L14-30 which will not plug into a AC300.

The EP500Pro has a L14-30A output receptacle.

See thus YT post on grounding issues with 5000es and the SolarEdge mid-point transformer.

Watch this on grounding the 5000es. SS is modifying or having GW modify the internal ground to neutral inside the 5000es
