Basically...if you're building a large solar system, get a mppt charge controller. For a small 12v system, get a pwm charge controller and a extra solar panel for better results. Nice video. Brilliant explanation of how both controller work.

Thanks mate - glad you enjoyed. You're pretty much on it. Even If you have a 12V system and get a higher voltage panel (like 38V) you should use an MPPT. A pwm is best suited to a 12V panel charging a. 12V battery.

Hi, I live in Liverpool Merseyside England and I use an 80 watt solar panel to charge my car battery without a controller. I use a blocking diode in line to stop discharge into the solar panel at night ok. Because of where in live the solar panel never never puts out much more than 13.5 volts, so great video but you should mention the fact of where you live because of the sunshine. If you live in the Sahara Desert yes. Take care Walter from Liverpool Merseyside England

Hi Walter - thanks mate. I should probably mention solar irradiance strength here in Aus vs other parts however the strength of the light should not affect the voltage as much as the amps. Your panel must have a low Vmp to start with. I would still use a regulator if I was you but it if its working for you then happy days.

24 volt system changes the whole equation, 31.8 volt panels match very well to pwm for 28-30 volt charging...simplicity and cost effective. MPPT is good for voltage matching, that's the main plus ...thanks for the demo⚡

Hey mate. Yes but I'm using a standard Victron DCDC 12 to 24V charger from the altenator. It pushes the power upto 24V. I feed this into the MPPT so it thinks its getting a solar panel at 24V. The MPPT then charges the battery. The only reason I did this was because i couldn't find a DCDC charger with a cumstom charge profile that could go up to 16.2V for my battery pack.

Hey dear I am facing power dropping issue in series connection. I have connected 340watt and 380watt solar panels in series to epever 40A mppt controller with 12v battery. It show power of one panel when I disconnect solar connector and reconnect, the mppt show both Panels. It’s hard to do this every morning. It was fine in winter but now summer starting and facing this issue. Using both panels form 2 months. after wire disconnect and reconnect the voltage jump from 33-36 to 75v. If something wrong with one solar panel then it should not work after replugging mc4 or solar wire in the mppt after that It work whole day but same issue next morning Both panels volts amps are little different.

Hi Mate - can you describe what is happening again? First in the morning when both panels are connected in series it is only showing 33-36 V on the MPPT? but if you disconnect the panels from being in series via the MC4 connectors and then reconnect it shows 75V on the MPPT? I will need to have a multimeter to do some testing. First thing you need to do in the morning is test the voltage going into the MPPT. Use the multimeter on the MPPT solar terminals and read the voltage, this is to check what the MPPT is showing is correct. Next, disconnect the panels from the MPPT (you can leave pos or neg still in the mppt, just measure one terminal and the other free cable). Do not disconnect the panels from series at this stage just check the voltage of the panels. It should say 75V. I can not understand at all how it would not.

Mppt used to stand by panels and starts battery power in hot sunny weather. After few days of troubleshooting issue resolved. I though battery sensor sending overheating message of battery and mppt standby the panel. But epever told me that you have oversized your mppt it’s 12/520watt max at single battery and my panels 340+380watt they told me to never cross the 520 otherwise it will damage the mppt. But solar panels never produce 100% I am getting 70-75% power. Mppt never crossed 40A. Reached to 39.5 amp and 574watt once after rain. Usually never crossed 520.

Hi Mate - what power station is it? Can you send me brand and model. My thoughts are you probably need to put it through a DCDC 48 to 12V (min 10A) converter. Usually they have an input Voltage range of 30-60V. You only need 10A. I'm assuming the power station has an inbuilt MPPT. You set the output voltage to 15V or whatever the minimum is on the power station and it will pull whatever power it needs from the converter which takes from the panel. I can't be completely sure though if the converter will like the fluctuation power from the panel. I could do a test run for you.

@sunbiasolaroffgridsolution6545 Жыл бұрын
Hey mate. Easiest one to answer. You can definitely have load on while charging. The charger will just deliver the power coming in from solar directly to load and surplus to battery or draw from battery to load if not enough solar. Now do you mean when you press the load button it turns the load on and off? Thats strange that the SOC % is changing. I would have thought maybe when you turn the load on and its being powered by the battery that the SOC % showing will drop because when a load is on the battery the voltage will drop slightly. The SOC % is just a calculation based on the battery Voltage. Can you do this again and tell me what the voltage of the battery is each time you do this? Eg 86% 13.3V, 56% 13.1V.

Hey mate. Question on the breakers in your videos. I'm putting a Noark Switch MCB DC 2 Pole 40A 360V non-polarised breaker on my camper van. Same model as you have here, a Ex9BP-N. Do I just put the 8 B&S - and + from the solar panel into the bottom of the Noark, (one each side ie. one to each screw) then out the top (load side) then connect the MPPT solar in via Anderson plugs like you wired up here?. (I want to protect MPPT and be able to isolate panels with the Ex9BP-N). I'm thinking of adding Andersons 50a connectors to the breaker wiring too, both ends so will have permanent Anderson connectors each side (input and output) of the breaker. Any issues in having Anderson connectors attached to the breaker wiring? reason, my MPPT then can be unplugged and taken out into the portable solar when not taking the camper trailer with me, example: going to the beach and just taking fridge, solar panels and battery, and of course the mppt. Also, last one, why the different breaker with red switch lever and not to same breakers ie. both Ex9BP-N's? Cheers!
@sunbiasolaroffgridsolution6545 Жыл бұрын
Hey mate. Thanks for the message. Yes you can connect pos and neg of solar into the breaker from your panels then out to the MPPT. An anderson plug on either side is also fine and a good idea for your application - ie to unplug and use elsewhere. No reason for using a different breaker only that’s what I had on hand. If you look at my other video I use a heavy duty battery isolator switch and fuses on the cable to isolate from the battery to the mppt/distribution. This is a better option over a circuit breaker if you have big loads from the battery - like an inverter.
