ask4bk:
Pls where did you buy it? I was just about to buy from aliexpress.
I believe you bought here.
All the ones i see here are modified sine wave.

Helep me abeg with source

From Valto(Xinboke) or Iinnov(easun) all Satchet inveters.
Valto also sells 500w psw board only (aggressively nice but can drain below 9v without bms).

Pnutmillionaire:
Thanks brother
There's an option on the deye inverter called "Bms_err_stop", it was unchecked by default, I checked the box this morning. This night the inverter tripped the house light off again but instead of the usual "f56 error: DC_VoltLow_fault", it threw an "f58 error: bms_communication_fault" which seems to be the origin of the voltlow fault.
So Im thinking perhaps there is an issue with the bms's firmware or the bms itself.

Point of note, the battery is 16kwh and has not been loaded with >800w when there's no sufficient pv

Why not test it without the communication ?
Set the charge values manually.

What model of Deye is it ?

Dam5reey1:
If you have an idea of how many units that version has sold in Nigeria that few weeks ago there was no stock, be it sms, sako, sunfied, PowMr, you wont say this.

Its only issues we post and see here. Thousands are enjoying their systems with no issues.

They have sold thousands of units does not negate the fact that Sako inverter is a poorly designed inverter. Why should an inverter fan be spinning that loud 24hours even with just 30w load. Why should an inverter be called 2Kva when it cannot carry more than 1200w. It is cheap, hence it will sell.

How do I do that ?

The model is deye sun-6k-og01lp1-eu-am2

Thousands of people no get issues.
The Fan noise no loud reach an industrial fan noise yet people over react to the inverter fan noise.
If you check this Thread you will even think say Deye am 2 no good as well, someone here has been experiencing issues with even DEYE SUN-6KW AM2 inverter, can you now say DEYE is also bad, we have thousands running fine.

they are really pure sine wave.

Final Setup

6kw Deye Offgrid
14kW Panels (3x605w JA Solar, 12x440w Jinko, 10x500w Cworth)
Victron 150/70 Charge controller
26.5kw Deriy Lithium and Cworth Lithium in Parallel with Busbar
Victron Smart shunt 300A
Junktek 100A shunt
Raspberry Pi 5 (running Solar Assistant)
Orange Pi 3 (running Solar Assistant)
Windows NUC (running Home Assistant)
Starlink for home internet
GLi.net router

Programmed Home Assistant using YAML for various automation, and created sensors from mqtt stream from SA. Influxdb for database. It also shows live individual power consumption of each devices in the house through smart plugs HA integration and custom auto-entites.

Since we going all in on renewable energy, gas hobs were replaced with ‘real’ induction cooker (max 3000w on highest settings with all 4 burners on, enamel cast iron pots).

Average daily load 30kW (Home Assistant programmed to do load management automatically, with pv forecast, so 3 AC, Induction hob, water heater, microwave , airfryer etc, every device is connected and will never exceed the 6000W rating of the inverter)

100 percent off grid, ie Island mode, no physical connection to grid. The wife is happy, I’m happy.

If you need any guidance on home assistant coding for your set up, you can private message me.

Hello Pardon my question please.

i thought its not workable to parallel two lithium battries of differnt brands.
could you please break down how you were able to safely acheive this?

also are the two batteries same capacity?

ask4bk:
Small cars need about instant 300-500A to start.
Bigger cars, SUV and mini trucks (eg hilux) could need 500-1000A. Imagine going higher to big trucks and lorries.
Lead acid have no problem with that.

For a few seconds, your LFP will comfortably do that.

Someone mentioned Juno starter kits, yeah, that's LFP or li-ion at work.

Polaris1:
I am familiar with Luxsun 24v, 4.2kva inverter but not with their battery
The fan makes a soft whoosh, my standing fan drowns out the sound. If you are a TV lover, you won't hear it. I'm not.
It powers my 0.75hp sub water pump pulling 1010 watts with no increase in fan sound.
But when I use the electric kettle 2500w, the fan revs up becoming a loud whoosh.
Idle consumption is 37 to 40w,
I would rather have the fan sound with mppt range of 60-500v to the inverters with 120-500v range.

Thanks for the feedback. Powering a 2500watt kettle is really impressive

I currently have 4 200watt panels connected in series to my 1kva inverter. Can I add 2 550watt panels to save cost to power a 5kva inverter

Sako's issues are on a different level compared to Deye, you can count how many people have complaints about Deye, but Sako almost everyone has a complaint or two

Total off grid

Duplex

Not cheap

Neat and well arranged as usual

This is 24kw of inverters, I suppose? Why exactly does a residential building need this much power.

Good day everyone, please I want to start my solar journey. I’ve been following this thread for a while and I appreciate your contributions.

I need the system to power a load of 600w and my budget is N1.7m, please guide me on what do. Thank you

24v inverter from Bread, Powmr, or Firman - 400k
3 units of 615w Jinko panel - 400k
Cables and accessories - 100k
Installation - 100k
Rest of budget on largest 24v Lifepo4 battery you can find

HB already gave you the best advice.
Bread 3.5kva will cost 320k if you are buying directly from the company. I think one of their marketers is on this forum.

What could be the problem with this bms.
The battery is obviously full from the voltage displayed but it states soc as 92%.
Although it hasnt exceeded 58V before, it used to show the correct percentage in respect to voltage.

Which inverter and battery do you use?
Change your password from default 1234( I think) to a new one.

I use deye inverter and a diy battery.
Ill try changing the password now

Not sure they have tbh.

I just changed it, the soc is still on 92% and every other thing is the same

Lol. I have four different brands of LIFEPO4 batteries paralleled together. I have been using it for 2years plus. You can parallel even different capacity as the internal resistance of each battery will tell your charger which battery to supply higher amps. Recently I connected the four different 12v battery in series(using an external equalizer) to make 48V 100ah, then I paralleled the 4 to another single 48v 100ah using a bus bar. Manufacturers telling you not to parallel their batteries with other brands is BS so far the batteries are thesame chemistry(i.e you cannot parralel Lead Acid with Lithium).

how long have u been using the 12v in series with the external equalizer?

Going to a year now

February 1st 2025, I stared this RE jonery after months of following this forum. Although am on lead acid and satchet inverter. Modify sinewave, which I will soon upgrade this month to pure since wave satchet one thou. Since February each time I see this as the investment that comes with peace of mind. I HV since disconnected there so called Grid. Soley on solar. I thank this forum onces again,una no know watin una don do for ppl like me. Like some one here always say "na who get sense the use solar"
