What Apexium boxes did you get?
link?
I had direct contact info for one of their sales folks, so my order was all via email. The box itself looks like this: https://www.docanpower.com/index.php?route=product/product&path=241&product_id=532
You can also get one that has standard M8 terminals (https://www.docanpower.com/index.php?route=product/product&path=241&product_id=579) if you ask. I have both. I should've gotten all the M8 versions. Nothing wrong with the connectors, but they're somewhat proprietary. I can get lugs anywhere.
If you're making your own cables and decide to order from them, ask them to add in a few sets of the connectors. I made my own cables with their connectors. I also have a custom set I made with M8's on one end and their custom ends on the other. Lets me hook a new battery up and charge with a Chargeverter before introducing it to the full pack.

Thanks

Catch, make or grow everything you can.
Translate to english: Someone is monitoring the sei with the base application.
I use Solar Assistant and I know many of the other SRNE members also use SA.
I think one of the guys mentioned he was using the SRNE monitoring software, but which member was that ...?
Edit: I think it was @apctjb who was using the SRNE software, for monitoring. Maybe we talked him into using Solar Assistant !?

¿Alguien ha conseguido un firmware actualizado para estas unidades SEI? Creo que mis unidades están desactualizadas y hacen cosas extrañas. Quiero usar mis baterías antes de conectarlas a la red eléctrica, pero cuando llego al 90 %, el sistema vuelve a la red eléctrica y recarga las baterías.

If you need update to the firmware - maybe best to contact the seller you purchased from.
In your settings if you set the return to mains voltage too high, they will switch while at high SOC. check your settings - most members will have the switch to Mains at low SOC such as 48volts or 49 volts.
You can post some pictures of the settings you have programed and we will take a look for you, offer suggestions.

dura = "lasts" ? celdas = "cells"
I think you mean your battery bank is 15s (15 cells) so runs at these lower voltages than a typical 16s (16 cells) pack.
When you charge up to "100%" and the battery reaches 53.2 volts, does the inverter SOC reset to 100% - ie does the inverter "know" that 53.2 is 100% SOC, or does it report a lower SOC ?
What is the battery type you input (ie the screen before the one you have posted) - if you picked LFP 16 then the inverter "thinks" your battery is lower SOC that it actually is all the time. On the main home screen it will display the battery icon and SOC. What do you see on the home screen?

How does the inverter apply Battery Recharging Voltage and Eod Recovery Voltage? It appears the system is backfeeding grid?

Interesting, I must have checked it at some point. Testing with inverter power showed 141A of inrush per leg and it couldn't start it.
HESP might run parallel but the ASP is different. PV with grid assist (MXLOD setting) or PV with battery only.

I took a pic of the battery settings page - here
@Jho210 Is your inverter set to LFP 15 ?
What settings are you currently using for the BMS Comm and Battery Charge configuration ?
Hola, estan configurados en protocolo BMS, opcion CAN, protocolo UZE, 15s. He revisado y reconoce bien mis baterias, incluso active la opcion de error BMS y de hecho al desconectar el cable de comunicacion el inversor corta la salida y marca error de comunicacion.
En general diría que los inversores para su precio están bastante bien con algunos problemas de software supongo, yo le he puesto cargas de 18000w y no hay problemas con la salida. Los problemas que he encontrado están asociados en su mayoría a un software inmaduro, ya que al interactuar con la red no hace lo que le pido. Mi idea es tener la red como última opción, que la red cargue mis baterías independientemente del tiempo pero que lo haga hasta que estén al 20%, otro punto extraño es que incluso con mi energía solar siempre hay pequeños derrames de energía constantemente y es algo que definitivamente no quiero, no es una unidad sólida en este sentido como por ejemplo el deye, en este mismo escenario simplemente cortan la energía de la red y entra hasta llegar a los valores que indicas. Mi red es muy mala con voltajes a veces de 100 o 105 por linea, esperaría que el inversor mientras suministra energía desde los paneles mantenga sus 120v pero simplemente está siempre conectado a la red y trabajando con los voltajes de salida de la red.

Hello, they are configured in BMS protocol, CAN option, UZE protocol, 15s. I have checked and it recognizes my batteries well, I even activated the BMS error option and in fact when disconnecting the communication cable the inverter cuts the output and indicates a communication error.
In general I would say that the inverters for their price are quite good with some software problems I suppose, I have put 18000w loads on them and there are no problems with the output. The problems I have found are mostly associated with immature software, since when interacting with the network it does not do what I ask of it. My idea is to have the grid as a last option, that the grid charges my batteries regardless of the time but that it does so until they are at 20%, another strange point is that even with my solar energy there are always small energy spills constantly and it is something which I definitely don't want, it is not a solid unit in this sense like for example the deye, in this same scenario they simply cut off the power from the network and it comes in until it reaches the values you indicate. My grid is very bad with voltages sometimes of 100 or 105 per line, I would expect the inverter while supplying power from the panels to maintain its 120v but it is simply always connected to the grid and working with the grid output voltages.

And for my own set up - Finally got the parts I needed to install the 2.5" x 2.5" risers from the main DC and AC trough up to the inverters.
As I noted back a few pages, I needed to separate the AC from the DC and figured it was easiest to do this with two separate AC and DC ducts.
Then I also figured it didn't make a lot of sense to run three side by side conduits from the inverter to the trough - easier to run the small vertical trough and use an end plate adapter.
- I spaced the AC duct off the wall 2-5/8" so the 2.5x2.5 had room to pass by easily to get to the lower DC trough.
So the upper PVC finger wire management is for the Comms, then the AC trough is below, and the DC trough below the AC. The DC rises up on the left hand side to the main disconnects - that go to the ESS1 and ESS 2 towers via 4x4 trough behind the battery banks, and on the right hand side the DC trough rises up the wall to allow easy connections with 1" EMT nipples into the PV disconnects.
Been planning for nearly a year, bought the inverters last summer, finally all up and finished on the wall.

Looking good! Very clean installation
A thing of beauty.

Can anyone confirm whether a 10kw / 12kW HESP can be used in a grid-tie configuration without batteries? I’d like to set it up for consumption/export since my utility provider currently offers netting. I plan to add batteries in the future.

Looks that way.

Great placement of the main disconnects! On the way out, even if running, they're easy to slap down! Is your computer setup dedicated to power management? Where have you stashed the batteries?Looking good! Very clean installation

no computer - just a monitor keyboard and mouse connected to the Solar Assistant on the wall - I bought a wall mount small screen swing arm, and added some brackets to hold a piece of plywood for the keyboard support.
I wired in a dedicated UPS plus - if the inverters are on, then this plug is on.
The batteries are next to the solar room in a dedicated alcove - double 5/8" Type X board, steel studs Roxul insulation - space for 20 packs on angle iron supports. The steel doors are under construction but not complete or hung yet. One step at a time.
This pic is out of date, but don't seem to have more current one handy.
Anyway - gives you the general idea.

Nice will be hooking up two of these in parallel pretty soon
