Hello everyone! I have been using a hybrid inverter Ecgsolax 48v 6,2kw for the past 2 weeks. I am very pleased with the low consumption from the battery and from the grid, with the mppt performance and a few other aspects. The review can be found here: This is the 3rd model I am testing...

Hey guys, I have been using these Winston 400Ah LiYFePO4 batteries in an 8s configuration with electrodacus bms for about 4 years now. Some people say these are the Ferrari s of lifepo4 because of the added yttrium. However they don't come cheap. Has anyone reviewed them? Do you know if Will...

Mine are grade B, purchased from China (OSN Power) through a friend from Romania. However, I have been using them for 2 years now and I am super impressed with the performance. A small 24v@40Ah bank (2*12v batteries controlled by 2 sbms0) is powering up an entire construction site since last...

Well, this is the place, Czech Republic, and, for me, no customs since I am in Europe. However, crazy expensive, brand new grade A batteries: https://shop.gwl.eu/LTO-technology/Lithium-Titanate-Oxid-Battery-Cell-LTO-2-3V-40AH-Cyllindrical-A-Grade.html

Good to know. Thank you, I will be in touch. Have a great day!

thank you! i have been using Winston for 3 years now (8 pieces of 400Ah) on an Electrodacus sbms120 cc very pleased with them. but they are expensive i am considering EVE for new projects, price is very tempting but not sure of their quality!

I recently bought brand new grade A EVE LF280K cells, 6k cycles with free shipping and tax free with delivery from EU warehouse in Poland. Vendor Cylaid Shenzhen Technology. Very positive experience. Those interested can buy (link is valid even if you don't live in Romania) using this link...

I am looking for a reliable supplier from Alibaba for these models: EVE 280Ah CATL 310Ah LTO YinLong 40Ah The low price is important, too. I read that Deligreen and Shenzhen Haomi and Shenzhen Luyuan are to be considered. Any other recommendations? Any warnings regarding these 3? Thank you...

I am looking for a reliable supplier from Alibaba or AliExpress for LTO YinLong 40Ah batteries. The low price is important, too. I read that Deligreen and Shenzhen Haomi and Shenzhen Luyuan are to be considered. Any other recommendations? Thank you

It did take me several weeks of writing emails and messages and sending videos both to the Epever factory and the AliExpress seller ...

Hi! Can you say anything about the standby power consumption of the Anenji 48v inverter from the battery and from the grid when it is not using the grid? Thank you!

I remember I restarted it manually after the sun was up, but still early in the morning. I never had the patience to wait and see what happens later since I have other options for that particular string (a triphase on grid inverter or a micro grid ac coupling system with a Victron multiplus)...

What you need is a Midnite Classic 150 or 200 charge controller. You will need to program a wind graph manually into it or load one from Missouri Wind and Solar if they provide one (16 different set points of voltage-amps). Midnite Classic 150 will support max 150 vdc and up to 95 amps...

Thank you!

I am interested in buying an Epever Tracer 5415 AN charge controller. Does anyone have any experience with it? Does it show SOC? Does it have aux contacts like Midnite or Outback? Thank you

I have known one for a long time - Czech Republic, no customs for those ordering from Europe, grade A brand new LTO, however crazy expensive: https://shop.gwl.eu/LTO-technology/Lithium-Titanate-Oxid-Battery-Cell-LTO-2-3V-40AH-Cyllindrical-A-Grade.html

Hi everyone, Any info available about the Easun solar charge controller rated for 60A and 190 Voc ? I am interested in power standby consumption, performance during cloudy days, how loud the fan is, at what amount of power generated it starts running, anything else relevant. I am thinking...

Ok. I will

Thank you very much. I ordered one, I will see soon how much output I get from a 340vdc 2300Wp string during a cloudy day

Thank you. Very nice graphs, how do you get them?

So, if I have Voc 110v on Midnite Classic, don't I need a 150V SPD for example? Instead of 600v SPD? Or did I get something wrong?

Thank you

I don't think so

Can you please tell me the behaviour of this inverter during cloudy/foggy days? How fast does it start production in the morning? Does it start production at 1 ... 5 watts like other good on grid inverters? Thank you!

Thank you! My SMG 2 is not good at all at charging during cloudy days. Same string on a Power One Aurora on grid inverter can produce 100 watt or more and SMG 2 doesn't do anything

thank you. I live in Europe, customs tax alone would make it very expensive i have been using Chinese mppt controllers for years and they only have a 1-2 watt consumption and they are running just fine, at a fraction of the price of the recommended controller which I am sure it is a very good...

Thank you!

Hello everyone! I need SPD with 2 poles on the pv side of the charge controller for smaller offgrid system. On the pv side: max Voc is 36vdc and other systems are max Voc 105-110vdc, what can you recommend? Thank you!

The cells are not 280 Ah, my measurements show 257 Ah between 3,000v and 3,550v. I am discussing a partial refund with the seller to compensate for the missing Ah

I have an Easun SVII (bought as Daxtromn Power BGH-5kw) connected to 48v battery working fine off grid I want to use it as an on-grid inverter without any charge to the battery and without staying on overnight When I am not at home I want it to feed power to the grid only besides selecting...

Hi, I just read the specs - Winston LiYfePO4 260Ah is about 9 kgs EVE LiFePO4 280Ah only 5.2 kgs? Yes, EVE is cheaper But is it worth the price difference vs quality drop? Has anyone made a comparison test?

Can you please name the good vendors? Thank you so much!

Thank you Janet!

Unfortunately Amy Wan from Luyuan Tech informed me they don't ship to Romania anymore because of Customs people making trouble. I had to find a vendor with EU stock, I went with Shenzhen Cylaid Technology (Gigi Zhou). They seemed serious. I should get my shipment in about 2 weeks

I want to install a solar panel of 30Vmp 400 watt on the roof of my Mercedes Vito van, and I need a good pwm charger that I can buy from AliExpress, preferably from EU warehouse, for my 24v lifepo4 battery. One that I can set manually. Can you please recommend such a controller? Max 20-30A...

Those interested in a hybrid inverter that works very well and is not expensive, maybe you should consider ECGSOLAX inverters. I installed recently 2 of them on different battery banks (24v 4,2kw and 48v 10,2kw). Very pleased with the consumption from the battery (especially the 24v 4,2kw one)...

Yeah, only 400Ah, 700Ah and 1000Ah like nobody else is making, and strong connectors too. Are you guys still struggling with the M6 bolts and nuts ha ha?

Hi everyone! Hangzhou Goosolar New Energy - does it ring a bell? They have some really good prices on Alibaba for lifepo4 EVE 280Ah and I am flirting with the idea of buying some, but I thought I would ask around first. Anyone bought from them? Are they to be trusted? Thank you

Can you set manually bulk charge voltage for this Amazon controller? I need 28v for Lifepo4, 8s configuration

My EASUN SMG 2 5,6KP on a string of 10 panels about 2300 wp and 322 Voc on a cloudy day has a peak of maybe 100 watts and below 35-40 watt doesn't even start or already stops production around 3 pm Is this a normal behavior for an AIO? Do you experience a similar situation? Thank you

Hello everyone, I am looking for a 24v inverter, something like mppsolar/pip/effekta, that can charge the batteries up to 32-33 v, and a similar one for 48v that can charge the batteries all the way to 65-66v. I am thinking about using 4s li ion modules in an 8s or 16s configuration. I know...

Thank you very much for your reply. Yes, orientation is not great. So maybe production can start earlier with a small load and the inverter on ...

Hello everyone, I have a Growatt min 6000 tl x grid tie inverter, brand new If there is a blackout during the night next morning the inverter shows 411 (02) error and doesn't start. I have to restart it manually about 10 times until it works again Manual says update firmware for DSP M3...

Dear Sue, thank you very much for your advice. I am aware that I should be cautious and ask for all info before purchasing. I am a little frustrated because I can't find many reviews for this particular supplier that has EU stock. Anyway, I might contact you through a private message. Once...

Hi everyone! I have been using solar and wind power since 2012. About 5 years ago I switched to lithium. I have been using solar controller and BMS from electrodacus.com, different models such as sbms100, sbms120, sbms0 in different systems, both on lifepo4/LiYFePO4 and LTO. For the...

Yes, I checked the fuse. It is ok. I disconnected the panels first, of course. I suspect that because of the small spark that occurs when I connect the batteries through the breaker, maybe one of the mosfets got burned. It is still a mystery. Finally the AliExpress store and the manufacturer...

Thank you!

Does anyone know the difference between these 2 models of Easun hybrid inverter? SMG II 5,6 KP SMX II 5,6KW They seem to be quite similar on the specs sheet. Or maybe the difference compared to other Easun models? SML, SV, etc ... Thank you

Please let me know if you are successful with that. I am thinking of doing the same. Thank you!

Hello everybody! I am contemplating dismantling a Volvo c40 battery and using it for solar storage. Has anyone done this ? Does anyone know if it can be arranged as 3s, 4s, 7s, 14s or another configuration? Thank you.
