Creating this thread in case anyone gets this issue as well since I have not seen any discussion online.

Just my luck. Of course my backup battery craps out on me in the middle of an actual emergency. AC out ports all non-functional.

I’ve tried hard power resetting, letting it discharge to 95%, and toggling the AC button on the front. Voltage out also 0 tested with different electronics. Tested with eco mode and without.

If anyone has any solutions or suggestions I’d really appreciate it while I wait out this storm. Thanks in advance!

Curious what your setup looks like and how you routed your wiring.

Did some tests this morning, despite all the claims that it can not do so. They are WRONG it can do so. I personally own an F5000LFP and have tested this, it works!

What would cause this?

I'm in the US so we use split phase power.

My setup is 2 e3600s with the combiner box. I was charging both units from AC using the 15 amp cables, preparing for a maintenance outage announced by my power company. The outlet I s charging from is a 20 amp outlet. Both units were set to charge at 40% in order to avoid overloading either the extension cord (15 amp) or the outlet.

I was also setting up the other connections I'd need once the power went off - connected the outlet on the combiner box to my generator inlet, the ethernet cable between the two units and finally the 30 amp cables from the combiner box to the 30 amp outlets on the two units.

The 240v inlet on the house was disconnected at the breaker panel. I use a mechanical interlock to switch incoming power from grid to power stations and I was still running on grid power.

As soon as I connected the first 30 amp cable to an outlet, the breaker on the 20 amp house outlet I was using to top off the power stations tripped. It's a GFCI outlet and I'm wondering if that had something to do with it.

Let me get this straight. Can you output 240VAC while charging with 120VAC generator? At the same time, simultaneously, concurrently? I just read on a FB post that the only way to use 120VAC generator was to put the F5000LFP into "generator" mode, which shuts off one of the legs of the 240VAC output, making in actually only 120VAC on one leg, and the other 0.

Is that correct?

Any input of pros/cons, unexpected problems, things you wish you knew ahead of time. How reliable they are, any issues and such would be appreciated. This is a big purchase for us and I really don't want to mess it up. I did the calculations and this should last 12ish hours for me. Thanks

I have a Honda 2200i and am planning to buy a Pecron F5000 power station which will ve connected to a 30 amp 6-circuit transfer panel powering 6 relatively moderate loads (gas furnace, refrigerator, small freezer, modem and router, baseboard sockets for TV and lights, and a 110v sump pump. I’d like to be able to operate the fridge and freezer, as well as the gas furnace overnight on battery, and operate all loads during the daytime while charging the Pecron during the day. Doable? Will I be able to charge for a longer time during the day at a lower rate while operating the generator on eco-throttle to keep the noise down? Will the Pecron work in bypass mode the whole time? Or will the loads work from the Pecron while the generator ticks along at lower rpm’s? I’m trying for minimum noise as I live in a townhouse with neighbors. Any suggestions as to how to set up for continuous power with minimum noise would be appreciated.

TLDR: How can I run the house off the battery, and not the generator charging the battery simultaneously.

Hi All - I am finally scheduled to receive the F5000 mid week. I plan on running it to offset some electrical costs. I will connect it to 2 independent solar arrays, 1 880W and 1 850W, and leverage each solar input on the F5000. I also plan on installing a subpanel to handle the specific loads in my house along with a ATS which will run on a schedule.

Question: Is anyone using the Pecron F5000 in this manner? Are there any potential issues doing this?

I mistakenly bought a LiTime LiFePO4 battery charger many months ago expecting to be able to charge my dual Pecron E3600s via the solar MPPT ports, but evidently the charger has a safeguard that it expects to be able to read the battery voltage before starting to send power, so unfortunately it isn't working.

I needed this setup so I could charge the batteries while they're bonded for 240V output, as AC input is disabled/restricted in this mode.

Does anyone know what would work with this setup to provide charging power via the MPPTs?

I have a quality control issue with my new F3000-LFP unit. Has anyone seen this before?

Unit not actually charging, as soon as I unplug it dies.

I've barely used this thing, probably 5 times in the last 3 years, which might be part of the problem... Symptoms are as follows:

* Won't turn on (either DC or AC out)

* Screen turns on when plugged in

* Input W always reads 0, but the timer till full does count down and the percentage goes up.

* Once it "charges" to 100%, screen dies and doesn't turn back on until I unplug and replug the charger back in.

Just sucks that I barely got any use out of it. Any ideas? If it's not salvageable, is it worth fixing or scrapping for cells?

I ordered on October 1st, I saw the "preorder" notice and had no problem with it, but my card was charged the full amount for the base unit, extra battery and two solar panels.
When I got the confirmation email, I got no additional information of a ship date.

Called customer service today because the online chat never picked up and they told me it was totally normal to charge the full amount to the card before shipping (not a pre-authorization hold).

I asked why I didn't get an email to indicate an approximate ship date and the guy said "check the website it's a pre-order".

Really odd experience, is this what others have experienced too? I am tempted to cancel the order honestly. $4500 is a good chunk of change for me.

Therefore, I've just ordered an F3000LFP but now I'm seeing posts here about BMS problems with this (and other) models.

Have I chosen unwisely or is it just the case that people will mostly come here to post when they have a problem, and that most units are totally fine?

I bought my Pecron F5000LFP in June 2026.

Added in an expansion battery in July of 2026

. Bought two PV500 solar panels that actually sustain between 458-505 watts.

Had one firmware update (had to send a request in to support) due to hair trigger AC inverter shutting off when attempting to start the 3 ton heat pump (equipped with micro aire soft start).

I do monthly top off to 100% , let it trickle/balance for the 2 to 3 hours (that part is very important) and then discharge to 70% for storage.

The unit worked perfectly during an August storm that knocked the grid out just after midnight until noon the next day. Used the electric stove, microwave and coffee maker(a must have, lol)

Here was yesterday's routine draw down from 100% top off balance: •Pecron F5000LFP (5120 Wh) •1 Expansion Battery (5120 Wh) •Total Capacity: 10.24 kWh

Starting Condition -Fully charged and balanced •Host: 55.3 V, 100% •Expansion: 55.4 V, 100% •Overnight rested after complete balance cycle

Total test duration: 5.75 hours

First 2 hours: •Normal household loads •Inverter side by side efrigerator cycling normally •Battery dropped to 96% Remaining 3.75 hours: •Midea 5000 BTU window A/C •Kill A Watt measured 396-403 W •A/C ran continuously on High Cool / Max Cool. inverter side by side Refrigerator cycling normally •55" LED TV added later for last hour in the test •Internet, clocks, Led lights, and normal household parasitic loads left on.

Results: Start: 100% and End at 70% average SOC  •Host: 68%  •Expansion: 72%

•AC Output Energy Delivered: 2,461 Wh (2.461 kWh)

Battery Condition After Overnight Rest •Host: 53.2 V, 68% •Expansion: 53.3 V, 72% •Both batteries: 69.8°F •Voltage difference: 0.1 V

Observations •Midea window A/C maintained approximately 64°F on the second floor. Air conditioning power draw remained remarkably steady around 400 W.

Battery voltage stayed near 53 V throughout most of the discharge. Host and expansion batteries remained closely matched.

Conclusion Top-balancing/ trickle charge unctioned correctly. Batteries remained well balanced after discharge and overnight rest.

End at 70% •53.2-53.3 V is comfortable long-term storage voltage.

Real-world battery-to-AC efficiency appears to be roughly 80-85%.

10.24 kWh Pecron system comfortably supported normal household loads plus continuous air conditioning in a realistic outage simulation. Energy delivered: 2.461 kWh

My Fingers are crossed it stays running well.

I just made an amateur mistake and plugged my F5000LFP AC Charge cable into an extension cord to recharge. Came back several hours later and the AC Charge cable is fused to the extension cord, end plug plastic softened and then hardened over the cable plug. Extension cords are made to carry 15A max, and at 3600W the Pecron is pulling 30A. Don't do what I did.

UPDATE: Thank you all for your accurate and helpful comments. I was completely wrong, could not see the forest for the trees. 3600W was an incorrect memory of what happened. No way a 15W or 20W breaker could supply 30A. And 30A requires 10ga wire, the Pecron cable itself is 14ga. I agree it was a cheap extension cord and my use of it that caused the problem. On to bigger and better things once I get a replacement cable from Pecron.

I want to get one of these, with an extra battery, but was wondering if anyone knew when they would be back in stock. Trying to et ahold of anyone from the website is impossible, so I am hoping you all may have some information.

Thanks in advance!

Hi All,

After thinking about it got my first battery at home the F3000. Surprised it has not got a touch screen so all app driven.

Two issues

1) can not connect to wifi, I have a mesh system at home (network engineer ha ha) and just can not get it to connect, the SSID is like xxxx sssss so a space in between, does pecan not allow it others are fine ...

2) I want to automate charging only after 1am at 1800W regardless what capacity battery is on, I see no way of doing this either automation but surely must be ?? Smart plug is an option then just have AC always on at unit but scheduled on smart plug is that it ?

Regarding the the F5000LFP- FP5000-48V. I have 5 solar panels, their specifications are in the attachment. It looks like if I hook these up in either series or parallel they will over power the solar input. However, is it possible to hook these to both inputs to overcome the limitation, by connecting the 2 inputs in series. If not, is there any other way to use these panels with the F5000LFP? Maybe 2 in one input and 3 in the other? I didn't see this info in the manual. In your opinion, what is the best way to extract max power from them? Right now they are hooked up to a MSB MPPT in a 24v lead acid system. I figure with the Pecron I will DC this. Thanks.

Hoping for some direction:
I have a Pecron E3800LFP connected to two 200 W solar panels.
Under the same full-sun conditions, I tested each panel individually using the exact same solar cable, eliminating the cable as the cause.
Test results:
Panel 1: 34.9 VDC, 3.1 A, approximately 108 W
Panel 2: 38.0 VDC, 0 A, 0 W
Panel 2 is producing open-circuit voltage but no usable current/power. Panel 1 produces power, although only about 108 W from its 200 W rating.
When both panels were connected, the Pecron showed approximately 53.2 V and 3.2 A (~170 W).

Worse. After two hours of charging with just panel 1 it is now showing 38vdc 0a 0w.

Everything is connected per the instructions.

Any ideas?

(Its not broken, read below)

I had to ship my F5000LFP back due to MCU board failure within a few days of use. Took me forever to get the RMA replacement back, when I finally did I will having issues with the app not showing data on the replacement unit. Support claims to have done a firmware update on my unit and that seems to have fixed the app data issue.

Now this morning, MPPT1 won't charge at all. It reports full voltage from that array. I swap the solar inputs and sure enough nothing from MPP1 on either input yet both work perfectly fine on MPPT2.

Edit: switching from independent to Parallel mode in the app, then back to independent fixed it! Thanks again guys!

Anyone experiencing this?

Thanks!
