Another perspective: 1) Per 6000XP spec. in theory: Two 6000XP inverters (while considering efficiency) could demand 268.8 amps (continuous) from three batteries - Okay. Two 6000XP inverters (per spec) could demand 497 amps peak demand for (5 sec) from three batteries however, your Battery BMS...

Opps! Be careful. Per 6000XP spec: AC bypass: 50A @ 240Volts (12,000W) AC Input: 37.5A @ 240Volts (25A @ 240Volts for inverter output + 12.5A @ 240Volts for charging battery) AC Output (nominal continuous): 25A @ 240Volts (6000W) -or- 25A @ 120Volts (3000W per leg)

I understand these lightning arresters from Midnight solar are quality surge arrestors. If your area is susceptible to lightning then its recommended. Especially if you know of equipment form your neighbors or yourself of being damaged by lightning. Installation becomes important (beyond...

18" for PVC conduit using individual THWN-2 conductors Schedule 40 PVC is commonly used for the installation of underground wiring to a detached garage or tool shed, or it can be used indoors like a garage or tool shed. The NEC requires heavy-duty Schedule 80 PVC on the side of a building where...

Was following this topic, however I wasn't able to understand your final solution after speaking with Current Connected. How much output current are you able to achieve beyond the 50 amp bypass?

Okay. My only point in asking was to make you aware of how you would bring the "Direct Current (PV) into your building". The new code rules (NEC 2020 690.31 (D)) require the use of "metal' conduit at the entrance point into your building up to your equipment (inverter or DC disconnect). Your...

Nice Drawing. Yes, keep with your #8 AWG THWN-2 wire size for your grounding conductor. Connecting the EG4-LL-S battery grounds to the internal 6000XP ground buss bar and continuing the connection back to the ground buss bar within your main service panel is correct. Additionally, you have...

@HighCountry Created four drawings showing your potential configurations based upon using buss bars or no buss bars as well as 2 batteries versus 3 or more batteries. When using two EG4-LL-S batteries with the 6000XP, the capacity of the two EG4-LL-S batteries becomes fully utilized under peak...

Just another view for a worst case perspective: Looking at the 6000XP output capabilities both peak and continuous. And figuring the needed battery power after factoring the efficiencies of 6000XP; 6000XP Output (W) / Efficiency = Need Battery Power (W) 6000W (continuous) / 0.93 = 6,452 watts...

Ok got it...thanks! So then, now I can see why the 6000XP bypass spec its at 50A. It assumes you can charge your batteries while running the rated load. Bypass current budget (if you'll allow me this term): 25amps (3000w) for running the load while in "bypass mode". 25amps for charging the...

@AZSolarJunkie, Thanks for your assessment of the 50amp bypass, I follow and agree. However, my curiosity is more focused on how a home system could be designed to make use of the full 50amp by-pass. While being limited to the 37.5amp AC IN specification. I feel I'm still mis-understanding...

Found this, a potential Protran 2 GFCI breaker solution authored by filterguy.

Out of curiosity, looking at the specification, it appears the 6000XP has an AC input limit of 37.5amps (9000W). So I can account for the 25amps (6000W) going to the loads with the remaining 12.5amps (3000W) charging the battery. So how does one make use of the remaining 12.5amps (3000W) of...

Good Job. Review notes: 1) Have a look at 2/0 AWG base amperage 195A versus 225A 2) EG4 Battey has a 125A double poll breaker but used as a 250A breaker (Positive conductor running in parallel within breaker). Per manual note 3) Panel modules wires are 12AWG ( I think) Hope this helps.

You have a choice depending upon how much "ByPass" current you intend upon using. From the 6000XP Spec. & Manual; Rated output current while in Inverter mode is 25A @240v. Max Battery Charging from Grid appears to be 25A @240 (after reading **115A@48VDC (AC) note & applying the 93% charging...

The lack of the internal circuit breaker protections seems like a missed opportunity for Sol-Ark at this entry level. Especially in terms of ease of installation. AC in Gen in AC out

Yes, thanks for opening my eyes to the imbalance issue. So....back to researching

Look forward to your findings on the EG4 6000EX-48HV

Thanks for the data point. I'll have a look at both these units. Yes, I agree on your assessment about the firmware and I'm following those discussions.

It seems that my risk is better understood if I knew how the EG4 6000EX-48HV is constructed. I may never know until I simply purchase the unit and make my own measurements. Naturally this is what I was trying to avoid. What I think I learning if a purchase the EG4 6000EX-48HV low frequency...

@RCinFLA Thanks for keeping me focused on my potential 120V load imbalances since my 240v loads do not contribute to this imbalance. I feel, it is this uncertainty that I'm trying to assess. Living in a suburban neighborhood with two other neighbors sharing an underground transformer in my...

... So.... a stretch question, looking to your experience, maybe cannot be answered (to be fair). How much neutral imbalance current can one expect from their home's service entrance grid? With the thought of adding a low frequency inverter containing a transformer? Let's assuming I...

Thanks! good to know. And yes! I would like to implement the common neutrals to stay NEC compliant. This brings me back to my initial concerns which may be tough to answer up front.

Thanks for response, it really helps to known prior to purchasing. I'll follow up on your suggestion of manufacturers who monitor the "imbalanced current" in the neutral (Xantrex, Outback). So...I'm curious...since I have not purchased yet. Do the manufacturers of other low frequency...

Any comments or past experience you can share?

Hello, I'm new to the forum, looking to implement an essential circuits backup system within my home. My system is not built or purchase yet, but I want to get a reality check. My power usage is currently being monitored and determined by a product from Emporia energy called "Vue". Emporia...

Got to thinking, maybe another approach in my setup, would be to limit the pass-through current with a 30amp double pull breaker (instead of 40 amp). For my application of supporting 10 essential circuits this may be the peace of mind I'm looking for post #8 to keep the 10awg wire...

Have a similar setup to what has been stated above. Slightly different. Looking for comments or guidance on my working decision to keep the 10awg wiring between my EG4 6000EX inverter & ProTran2 transfer switch. Yes, I can always go with rewiring to 8awg gauge but I was looking for some...
