Please be so kind to specify which better alternatives you are referring to

Regardless of the power of the inverter, aren't you supposed to set the max battery charge / discharge current in the inverter's settings so that it does not exceed the max charge / discharge current of the battery? Relying on the BMS to do that job doesn't seem a good idea to me. In my view...

Before I buy anything, I will start by installing this nifty little device and record my consumption / peak power etc. Found this for P1250 on Shopee, should do the job. They also have a DIN rail version that has Wifi for a permanent install. Click on picture for link.

Yes 16 cells fit in there and they offer to customize it with the BMS of your choice (JKBMS among others). They can also do the entire build for you with the cells of your choice. This manufacturer makes metal enclosures that could fit 32 cells for a 2p16s built, although you would have to add...

I thought in Lipa you hardly have any brownouts? That's a big battery if just for the occasional brownout. But maybe it makes economical sense to use your battery at night to feed your loads, if the deal you are getting on the net-metering is not that good. Have you already started the process...

Nice find. It might suddenly become more difficult and/or expensive to purchase batteries directly from China. Not just Nigeria. Two of the big freight forwarders of Chinese goods to the Philippines also currently refuse to ship batteries.

My forwarder said he is waiting for clarification and that I should contact him again in September. But if you read the text, they are even banning gadgets that are powered by lithium batteries. Looks like an excuse to decongest their ports imo...

Her reply: "Yes, I heard about that from the freight forwarder to Nigeria" So it's true ?

Is this from your own firsthand experience? Because Deye support was trying to talk me into purchasing a Chint-3P meter as being the only compatible one with my hardware... But they're expensive compared to the single phase ones...

I'll drop a message to SA support see what comes out.

Yes I agree but a catastrophic discharge current (short circuit on the load side) seems a lot more likely than a catastrophic charge current (other than maybe from lightning, which the PV circuit should be protected against)?

True and very good point. Are class T fuses non-polarized?

Is deye.com even a legit website of Deye? Their official website is deyeinverter.com and their official alibaba page is deyeinverter.en.alibaba.com and these pages make no mention of these batteries. There is also a deyeess.com website. Looks dodgy too.

I am the OP and this thread has drifted a long way off topic ? But while we are speaking about apocalypse and the likes, has anyone read this blog (which also very much relates to renewable energy by the way)? Very interesting read, compelling arguments imo: https://dothemath.ucsd.edu/ Maybe...

I just bought this for $22, haven't received it yet. You can connect to it via Bluetooth with a phone or PC using their app. Not sure if it does long-term data logging or not, will report back once I try it. Might be possible to hack it and access the raw data it sends over bluetooth and log it...

After digging and digging I have become nearly certain that the Deye acts as an online UPS for the backup load. The backup load is always powered by the output of the inverter, whether the grid is up or not. Therefore when the grid goes down, no transfer of that load occurs (same as an online...

Where did you purchase your Deye (and at what price if I may ask)?

Hello, Is it possible to run the Deye as an offgrid inverter and only switch on the grid when needed to charge the batteries? I see in the battery setup that there is a "grid signal" feature, which could potentially be used to control an external "normally open" relay or contactor to connect...

Where do you get those yellow bus bar protectors?

Co Could you do a test: at night (no solar output) when your backup load is powered, disconnect the battery. Does the backup load remain powered or not? If you think of the inverter as a giant UPS, this is how it should work: https://www.kstar.com/indexproblem/18614.jhtml "When the UPS...

Reviewing the document below, specifically the note about the accumulation / saturation / absorption stage on page 5, I notice that most popular all-in-one inverters (Deye / Sol-Ark, MPP Solar, LuxPower...) do not seem to have a setting for the accumulation stage cutoff. They however all have a...

Can't find a boost setting either for the Deye or MPP Solar, and at a glance also not Luxpower (TBC). So does it mean that these three just switch off altogether right after the bulk stage without holding the absorption voltage at all?

Did you use the shipping provided by the Alibaba suppliers? Let us know if you get hit by duty and VAT please.

So thinking about it a little further, I kinda wish the Deye had integrated ATSs to move the "backup load" to "on grid home" automatically whenever "backup load" wants to pull more than 50A total. This way, the 50A limitation would be gone (as long as the grid is up obviously). Once the backup...

Neither Docan nor Quishou have EVE cells at the moment, only CATL. I asked Docan about certificates for their grade A cells and they cannot provide (unlike Amy at Luyuan Tech). Luyuan has EVE cells but the grade A are very expensive. Anyway, regardless of the supplier, my plan was to have the...

That is what is getting at me with pre-built packs: how do you know what you are really getting if they do not provide the certificates / QR codes of the cells? Many of these packs also have welded bus bars which makes them extremely difficult to service should you have a bad cell in the pack etc.

For inverter, I am lurking at the 8kW MPP Solar 8048MAX. I can order it directly in Taiwan from MPP Solar and my freight forwarder will ship it to me in the Philippines. Would that do the job? https://www.mppsolar.com/v3/pip-max/

That was it! Completely missed it, thank you!

Thanks for doing the test. However this still doesn't really tell us whether the backup load is primarily powered by the grid when the grid is up (grid consumption possibly being offset by the production of the inverter if in "zero export to CT" mode), or whether the inverter is the primary...

hmmm reading the Sunsynk manual, which is a Deye rebrand I think, it seems there is an absorption stage but it seems the cutoff (current or time) cannot be user-defined? From the Sunsynk manual:
