Missing link

We installed a 5deye at a clients. and the 3000 also communicated via CAN on its own after link change and cable change plugged the comms into the RS485 Lo and behold Pylontechs "change comm mode to RS and that is with brand new us3000c

The Sunsynk is the british/ eu western brand for deye, Deye anounced that after 10 years they will replace a faulty cell obviously courier not included. I Whole heartedly agree with your cfe results and statments same experience multiple sites, deye batteries are almost drop-in for GLA's but the reliability is excelent.

i have also now heard about an issue of having both supply and return conductors in the same sleave. the heat shrink is correct thought, 2" from the termination point. Say for instance red on the yellow return and black on the blue. they state cross induction as a issue busy going through sans again still can't find the ref. maybe the building code may shed some light or the sseg Draft regulations

All high C rate units have liTiO this because of “ELECTRIC VALENCE” if you understand the concept and periodic table enable high electric transfer or C rate. Sirius in the background that is hidden from your eyes consist of normal EDLC of about 40F each. Just the control ie solid state I a proprietary thing. That is why WEST could build their units just now with MFB and Wi-Fi. Toyota is going for the Hybrid Supercaps since with the 37.5vdc to 58.2 range is a drop in and as high as 6C rate such as E-Prix that managed to blow 5x 1MW generators. they keep the hybrids to 2C max due to domestic use and safety. With a guaranteed 100% cycle at maximum C rate of 50000that is 100 years with 100% use every day.

Go to the Battery menu and at grid charge , de-select grid signal that should help

I may have used wrong wording it is the Lithium Mode 00 - 16 for CFE

Anyone know what the battery selection of CFE'S are on page3 of battery setup on the Deye

Guys ever thaught of using 4x12vdc fans in series then it will run straight from the battery pack(⁠•⁠‿⁠•⁠)

Yes on the previous Deye units we have taken an unbound dongle and bound a Deye solarman PV wifi and bound it to a sunsynk successfully. Alternatively unbound dongle from the one install and then use it on the other unit. Option 3 is if it is the same site use the healthy logger on the new inverter without loosing the data, just keep track of the date, viola you have a spare logger.

9x 535 will push you over the voltage limit and damage the mppt 9x49x1.14 = smoke. While 8x49x1.14 will just make it on the voc of the inverter. The 1.14 is for morning cold start. Run 5pv x4 string 25A hard clamp fuses maybe midis and 6mm² wirr and holders. Generally the unit will take between 110%-130% of current as with victron mppts

Everyonne should keep in mind that inverters, (most ) are ddesigned with ,2500Wp pv's in mind. Canadians Pv's has a ratio of pv voc x 1.14 at -10degrees C, so its pretty easy to blow your mppt witth voltage on a cold Clear winters morning!!

A good example is victron that internally ensure disconnect and maitaning the bond. With our utility supplies being ripped apart by theft we see higher and higher e-n elevations. We had 430VAC running through our block a couple of weeks ago when the idiots stole the neutral and now sit with a 5-10vac elevation from the main supply. Take a look at deye inverter suggested e-n bonding relay setup. On their site manual.

If you are running pylons you MUST get get a victron can to can supplied by victron typeA CATe CABLE the victron side will be blue and the battery can side will be black. DO NOT use diy cable they create error or my damage your ccgx can interface. Pylon should be setup 44.5 (bmv battery activate here) and max for the victron is 53.2. just se victron site on the setup.

The panels have stc and noct = standard test conditions and normal operating conditions. The latter is more reliable figure. Ex. 330Wp = Voc and about 8.73A/hr short circuit. So real world you can get 90deg solar angle mid day max power of about 295W. Parallel ups the amps, series ups the voltage and lower the power loss we run 2 mppt one at 820Voc-10A and 680Voc at 10A. Static angle, we have reached 84.5 KW days with blue Skye's
