Hi Rick24, So the Synapse 3.0V+ Inverter which we have with the loud fans, has 2 wire fans and the suggested Fan Speed Controller from Aliexpress can handle 3 wires. What do I do with the third wire connection as the fans only have 2 wires. This one is almost identical and DC has input SOUT - what does that mean and on the right wires to the fans (3) it says SIN - what does that mean It looks hard to program. Take a look at this one also 2-3 wire. With an LCD screen. What does DC intake direct S/PG mean and to the fans S/PG? Thanks Rick. Regards, Stephen Mannheim

Hi GMAC, I have bought the 2-3 wire fan speed controller from Aliexpress, exactly the same as in your post above. So there are 3 wires from the controller for the fan and the Synapse fan only has 2 wires. What do you do with the third wire where does it connect to? Thanks again, Kind Regards Stephen Mannheim.

Thanks GMAC I will have to send it back. Thanks.

Hi GMAC, I ordered a part from overseas and I received a different product from the one I ordered. I tried to order the one below and got the one further down the page. The 4 wire controller. And I received this one> Will this one work. It says above that it cannot control 2-3 wire fans in the writing above. Can you let me know. Regards, Stephen Mannheim

Hi GMAC, Could you take a look at the 2 links for controllers in South Africa below and see if it is the right controller I am looking for, otherwise I will just have to wait for the AliExpress controller to arrive - around a month. I have not ordered it yet. But I have ordered; a little while back, a CPU for my iMac from AliExpress and they are quite good. Just the wait. https://botshop.co.za/products/w1209-temperature-controller?variant=42891656954096&currency=ZAR&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&gclid=EAIaIQobChMI-bLi7vjY_wIVlfp3Ch3pNQzHEAQYASABEgLES_D_BwE https://electromannsa.co.za/product/w1209-digital-dc12v-temperature-controller Thanks sir for all your help. Hope to hear from you soon. Best Regards, Stephen Mannheim

Is this the only controller that will work? So I must buy 2. It is rated at 12 volts and if you buy 2 it makes 24 volts? Do I get an electrician to install it or someone who specialises in inverters?

Hi all concerned, How do I go about regulating the fan controller for this Synapse. Is the AliExpress Controller the only ones that work? The Botshop and Electromann controllers mentioned in this thread will they not work the same? There was that person who had this same Inverter and they manged to actually control the speed of the fan to a point where they could barely hear it. If anyone knows the answer please enlighten me.

Hi there it is Stephen mannheim here to Semaj76. I see you made the mod on the SYNAPSE 3000VA/2400W (V+) 24V Off-GRID Inverter. I see you had a link for the Botshop and Electromann for the fan speed controller. Is this the same item that Aliexpress sells? Ours is this same inverter below. "The best advice I can give for those that has bought this noisy inverter and is stuck with it is just to order 2 temp speed controllers . Power the controller from the wires powering the fans and mount the temp sensor on the pv and inverter heat sinks inside. Set the speed control temp from 30 to 50 Celsius.' We also have some lights on in the apartment, a Mac computer, 2 laptops and the fridge. So have you sorted the noisy fan problem with the kit from Botshop or Electrmann? I see they are 12 volt and ours is 24 volt - how do we make that work? - you mentions buying 2 controllers? If we have the same system with the same problem then is this going to work for me? Also who did the installation for you? Kind Regards, Stephen Mannheim. Hi there GMAC, it is Stephen Mannheim here again about the noisy
