Hi !
We got this response from Dongguan Lightning for a new order of EVE LF280K order.
Anyone can confirm that this B in the QR code does not mean it is GRADE B cell ?
So this only differentiate cells sold for EV or solar ?
This is a non US inverter.
So it is an Off-grid (with grid support) 8kW, dual MPPT inverter for 220-240V 50-60Hz systems.
The successor of the previous MAX 8kW inverter.
That inverter is also the base for the US LV6548 inverter ...

I think I live in an off-grid stone age here in the middle of the EU. ?
Really, the utility companies (and government) is stuck 10-20 years ago.
They are stuck in the separated off-grid (an inverter can only have DC-battery and AC out connection) and the AC coupled hybrid era (need extra PLC to...
This happened to one of the members in the Hungarian off-grid community.
OP has two 24V LiFePO4 packs connected paralel :
- 280Ah EVE cells with JK BMS
- 160Ah with cell level BMS
Batteries where charged by:
- MPP Solar 3024GK inverter with 6 solar panels
- Epever 6420AN MPPT with 4 solar...
Hi ,
OP bought and installed a new PowMr WM5k-III inverter about a month ago.
Used it with 9 solar panels:
- 6pcs of 410W, 49.5Voc, 40.9Vmpp
- 3pcs of 390W, 45.06Voc, 38.01Vmpp. One of them was connected to a TIGO optimizer (because of shadows)
All together 432Voc, (would be 475Voc in -10...
Hi !
I have a problem. Here are inverters only allowed if locally certified, or if they are galvanic isolated.
And I do not know if the MPP Solar inverters (like 5048 GMX or MK) are galvanic isolated or not.
Any info ?
Hi !
I am planning a grid-tie and an UPS system.
- The grid-tie 5kW, 15 panel 350W serial (all 40Voc ... so together 600V) with Fronius or SolarEdge or other utility allowed inverter. (no hybrid inverter allowed)
- UPS with MPP Solar inverter and 16x LiFePO4 cells 3,2V 280Ah (48V)
- SCC that...
Hope this is the right topic.
A company popped a question if they can use all-in-one inverters as UPS for they server racks/room (with LFP battery and PV)
For my own little servers I use the MPP MK model as a double conversion UPS
But for big like a rack full with 3U Dell servers ... I have...
Hi
I am searching for a solution.
I want to make a grid tie system, that sells power to the grid. And a separate UPS system with MPP Solar inverter and lithium batteries.
The possible grid tie inverters are limited, so no MPP Solar for example, but many Huawei, Fronius, SMA, Solaredge, SAJ...
Hi !
I want to build a 48V system with 16 EVE 280Ah cells, and 1(-2) MPP Solar inverter (5048MK aka Axpert King)
But I want this system as an UPS. So no daily charge and discharge.
I think battery to last long I charge it to 60-70%
I know inverter is stupid. It has only the sum V of the cells...
Hi newbie here
I have some questions about BMS
I want to make a 16s 100A 48V system (Fortune cells) mainly for UPS reasons. And safety first ...
1, Is there a way to monitor the temperature of all 16 cells? 16 temp sensor ?
2, a 150A BMS is enough for a 100A system (like this Daly...
Hi
I am searching for a dual power manual transfer switch ... for 230V 50Hz EU system.
Something like Reliance in US ... very-very like that :D

(the extra circuit breakers in it ... I do not think I need it, but who cares...
Hi
One of my friends want to make a small night light system (offgrid).
Already has:
- 1 piece 305W 40Voc solar panel
- 1 piece 12V lead battery 70Ah
- 1 piece 12V LED street light (self regulating with night switch and movement detector)
So he needs an MPPT (30-40A output).
Will this be too...
Hi,
I want to build mostly a UPS (for computers and some home appliance) solution with 280Ah cells (16 pieces, 48V) and MPP Solar inverter (parallel 2 inverter).
I looked on the MPP Solar PIP 5048 MK model (EU):

Not a joke :)
Here is a little video with measurements demonstrating it:
In Hungarian language, but in a browser you can turn on subtitles and set it to Auto translate to English
What you see is a simple setup. From left to right
