Hi guys, i have read so many different numbers on current consumption of the JK BMS that i am confused now:unsure: Could someone please sum up the consumption of typical kinds of JK BMS with Bluetooth on/off and in stand-by mode? Does it consume anything at all if it is switched of via the...

How much would the protrude? Keep in mind the extra windforce if it can easiliy catch up under the panels! I am not a static expert, but generally speaking this is not recommended. Depending on your local situation (windy area, much snow?) i would rather except less solar than risking a damage.

What about the fan noise with the Xijia and FCHAO inverters? When (at which load) do they kick in and would you hear them - say from 5 m away?

Thank you for your experience. Yes, i know especially the chinese brands tend to overrate their products sometimes by 50% or even 100%. You should carefully raise the load to see what it can handle and measure the temperature at the components. There are also more reliable brands for 2 or 3...

No problem at all. I have a little test system with a 50 and a 130Wp panel (in parallel) - even they have slightly different Voc and Vmppt. I even sometimes use them in series (50+130 in parallel) + 130 in series.

Hi all, i need an inverter for 24VDC to 230 VAC 50 Hz. It should be able to deliver 1000W cont. and maybe 1500W peak. It sould have a good pure sine wave and work quietly up to 800W or low noise fan. Are the cheaper china inverters o.k. or are they more fake (Toltakien, SUSWE etc.)? What can i...

Honestly i have more trust in my own diy batteries than in the system batteries from some doubtable producers. Sure, you will never 100% know how your bms of choice works and if it may get faulty components. The same goes for software, firmware and any release upgrade. I even built some diy...

I would go for a complete diy battery with LFP prismatic cells from china. They come very cheap nowadays and you get 105 Ah cells for 30...40 bucks! Add a bms for 100 bucks and you are ready to go! For 8 cells (= 24V ... 28V) you get 2.75 kWh for a price of 350...400 bucks. I will build a test...

Look up the surge current your saw draws! Big motors can draw an immense surge current for starting due to induction! Is it a 3phase engine? Does it use a capacitor? You can try to add a surge current control device to reduce the initial surge current. There are several types availabele. Also...

Never heard of JDB BMS. What about JK? Imho the simpler the more stable and reliable. Software can be faulty (there was recently a bug/flaw in JK firmware where LFP-settings were automatically reset after a longer idle period back to li-ion without any notice!). I would like to have it as...

Hello, i want to build my first LFP battery (for testing purposes) and want to equip it with a rather simple BMS for protection (deep discharge and overcharge) with capability of 40...50 Amps. It doesn't need to have any software or programmable features but should be as efficient as possible...

Sounds really good and i would be interested. I could probably not contribute really much, but maybe some ideas. I have some basic knowledge in electronics including simple circuits with transistors, mosfets and build some easy power supplies. I even modded some heavy server power supplies to...

Yes, thanks. Most consumers are single phase (230 VAC), only the oven in the kitchen uses all 3 phases (and can be run on grid only). What is the idle power of the victron inverters? If i only use 1 phase, power is limited to 230V x 16Amps (below 5 kW). If we get a 8 kWp PV installed in 80+% of...

Hi all, we are planning on a new PV-installation on our south-east roof, estimating 6...10 kWp of solar power. We also plan a diy battery (LFP 16 cells, 280 Ah, 48V) and look for a decent hybrid inverter with very low stand-by consumption (night use). We live in Germany in an own house, so we...

Nobody here who could help?

Hi all, i am new here but have some experience in electronics and Solar power. We drive a big solar generator on a big barn roof (about 1000 m2 and 92 kWp) and a small testing PV (300 Wp) on our roof. My brother wants to build a small solar driven RV, about 300 - 400 Wp with a 150 Ah LiFePO4...
