Hey Ray, I've had this exact same MPPT charge controller since the early spring of 2019 in my truck camper. It's branded as an Armada 40 and I was happy to pay $259 cdn at that time. I have it setup with 2 x 300 watts 24 volt solar panels run in series and mounted flat on the roof. It charges our 2 X 420 amp hour 6 volt Rolls AGM battrries connected in series for a 12 volt system. We've used the camper year round since then from Vernon, BC in summer and the South West USA in winter without any issues. We have a 20 amp breaker on the solar side and a 40 amp breaker on the battery side. I for one love it and would buy it again. We hope to bump into you again like we did at Saddle Mountain BLM back in 2019. Enjoy you trip south this winter.
This post is easily the best as far as setting the battery type buggered if l could see the symbols so this got me set up for lithium as it was on lead acid..mine is a 20 amp kick ass same difference but without this post l would never had figured it out fro. Manual alone. Nice one mate thankyou 👍
Nice review Ray. One thing that sticks out to me about this controller is its physical size, the thing is huge, but that might be a good thing for component reliability in the long run. I don't have anything good or bad to say about it, but one test I'd like to see you do is overpower it with solar panels since you have more than anyone. I have 6 - 200 watt 24 volt solar panels feeding into 2 Victron 30 amp solar controllers and so far so good, but that is more than they're supposed to handle.
Will do, I tried 940 watts feeding the previous smaller size 40 amp controller and it performed well, it just doesn't pass any extra wattage and only maxes out at the 40 amps charging current. The SRNE have over voltage and panel wattage protections so you can over panel them. If they heat up they also have temp protections and will reduce the current until the controller cools down. Tried that when we had 104 degree weather last summer.
Thank you Ray, always nice to see your good work and reviews 😊. There is so so much stuff out there!! How will I ever choose new batteries and add a solar panel 🙈. So much to choose from !! If I go lithium does the converter needs to be replaced? The inverter? Thank You for all you do. All this while being on the road and taking care of regular day to day to do stuff, taking care Anne :-0). You have super energy level. Take good care, safe travels. Cheers 🌞
You're welcome, yes, it's amazing how the product offerings have grown. It is generally a good idea to get a converter that is desined specifially for lithium batteries but may not be totally needed depending on the model of lead-acid converter one has. For example, my OEM does a terrible job of charging my lithium batteries but my aftermarket InteliPower with manual boost can be used quite well for the task. So I haven't need to change. Here is a video I did explaining and demoing it - www.loveyourrv.com/lithium-battery-charge-test-can-you-use-a-lead-acid-charge-converter/ Cheers! Ray
@@LoveYourRV Thank You very Ray. What I find confusing also is the kind of answers I get while consulting a store. The things they tell sometimes,,, The lack of knowledge. Especially back home in Quebec where there is very little of everything. Have you heard of Volthium Lithium self-heating batteries?
No, can't say I have heard of them. I don't think most RVers need a self-heated battery. Just wire the lithium batteries inside the living area of the rig or add some heat to the storage compartment they are in. The beauty of lithium batteries is they don't vent any gases and can be mounted in any orientation. So they don't need to be outside.
@@LoveYourRV Yes indeed, I lack space inside. I would have wanted to leave them outside. I do hit -15C sometimes in November back home. But I will recheck under the bed by the inverter. Doesn’t it emanates some sort of electric or electromagnetic field, something that could be a sleep or brain- body disturbance?
No, lots of people install the batteries under the bed. If worried you could always install some reflective metal shielding, but really a phone or laptop will emit more radiation since a person is so much closer.
Hi, thank you for the vid, it's excellent!! Better than vids made by fellas in Australia. I live in the land down under, Australia. We have that controller here it's sold by a company called KickAss 20A $120ish and 40A $190ish, it's rebranded as KickAss here. I have the 40A model. A few questions if ok. What size cable did you use from the solar panels to the 40A controller? Similarly what size cable you use from the 40A controller to the 2nd battery? Lastly, you answered one question, you fitted a 40A resettable circuit breaker from 40A controller to the 2nd battery. BUT you didn't mention what size resettable circuit breaker you used from the solar panel to the 40A controller? Cheers, Steve
I'm using 6 gauge for the controller wiring from the panels and to the batteries. Between the solar panels and the controller I don't have a breaker I'm just use battery disconnect switches. If you're interested you can view my current full off grid power system here www.loveyourrv.com/our-rv-boondocking-power-systems-current-state-of-things-2022/ I recently did an update video on it while camping in Utah.

Aloha Ray, we were wondering if you are gonna head back To California since borders are now Open, we really enjoyed it past videos of Canada and California.... Mahalo from Big Island Hawaii 🤙🏽😁
Your video is a lifesaver! I live in Thailand and don't have access to many MPPT controllers save for this one. Before I buy it, I needed a rundown in English and this helped so much. My only question: If my lithium battery is completely drained, will this work on initial startup? Or do I have to charge my lithium battery first? My original (and very cheap) MPPT controller failed and my battery drained down to 3.7 volts. Would it be dangerous to attempt to recharge the battery? Is it considered fully discharged at this point and unsafe? It does have a BMS in it for overcharging and over-discharging protection, but now I'm worried it's damaged.
Best to ask you battery manufacture about that. If it is a 12V type lithium battery with BMS it should have cut off at about 10.8V not 3.7V seems awfully low.
I have my roof panels wired in parallel versus series so need a little more wire thickness. So I have 10 gauge from each panel to a junction just below the roof, then a 6 gauge run down to the controller.

I'd assume that when the controller auto recognizes that its connected to a 24V battery versus 12V at hook up it would automatically double all the parameter settings. Maybe the manual didn't list them. You can contact the company here for confirmation www.srnesolar.com/contact-us
How do I set the battery charging mode? Just bought my first trailer (used) and it came with this one. Got a error 1 code which is battery is discharged
You have to enter the settings mode and select which type of battery you have Gel , Lead Acid , or Lithium. Or for experience people they can enter USE mode and set custom charge settings. It tells in the manual how to enter and select and save settings.

If you add 15 to the Celsius number and then double it its an easy to do rough calculation not totally accurate but puts it in the ballpark. :) For example 15C + 15 x 2 = 60 F or 25C +15 x 2 = 80F and so on

@@LoveYourRVthank you so much for the manual super appreciate it I have another question when the Sun goes down do all the lights turn off the charge controller second question what is the power draw if left on during the night
In the manual, the spec for No-Load Loss says 0.7 W to 1.2W. As for the LED lights, the solar led goes off at night, and the load goes off if there is no load set, but the battery LED will stay lit as long as the battery is hooked up. But power loss is minimal so I won't worry about it.
@@LoveYourRV thank you so much for your reply as I have light still on at night time this means I must have it hooked up wrong or settings not off I'll recheck the manual thank you
Usually no, if it's a 20A SRNE MPPT charger, then the battery charging output will max out at 20 amps, so the solar input will be lower than that since the solar panel voltage is usually higher than the battery voltage.
@@LoveYourRV MPPT Srne 20 Ampere, given input of 38 volts 13.5 Amperes, to charge a LifePo 4 12 Volt 100Ah battery... I wonder if it is safe to make the MPPT yourself...
No, it supplies DC up to a max 20 amps. Its basically a way to control a DC load. It can be set to turn off when the solar stops at sundown or set for certain hours of the day or all the time, manual switched or off. When used without the solar charging the batteries then supply the power. One use case is to power lights on a timer. I use it to power my tire pressure monitor repeater. I have the load set for manual operation so it acts like a switch. Cheers, Ray
hi sir..is it possible to charge one battery with two solar charger control i mean two system..but the same 12v but differ on panel wattage? i have two separate system the same 12v. one is with mppt 40a 550solar panel and the other one is 20a mppt srne with 200w panel..is it possible??
hi sir..is it safe for the battery using double charger 40amps srne? i have 2s2p lvtopsun battery for now 24v 200ah..and i have 2 charger 40amps srne with 1100watts each charger..Im too worried about the charging current as to the heat of the battery since some of the lifepo4 battery max at 50amps charging only. But when i scan the data sheet for my battery it can continously charge upto 100amps..Since i have this set up somestime it charged at 35amps each scc..so total.of 70amps.. Is it.safe sir our battery with this c condition?
I'm not sure, best thing to do is contact the battery manufacture and ask them. My guess is that it safe but may reduce the lifespan of the battery to charge it at high amps too often. They usually have a continuous charge rate specification for long life and then a max charge rate.
здраствуйте. хотел бы узнать. у меня такой-же контроллер SRNE. подскажите пожалуйста. если отключиться бмс от кантралера то он может сгореть я выставил зарядку на литий индикатор синий. а акумуляторы у меня lifepo4 железо фосфатные. он не сгорит при отключения бмс? или какую тип батареи выбрать под литий подскажите?
I don't think your Progressive Dynamic charger is designed for Lithium batteries. I changed mine to the lithium version to get the full advantage of the batteries.
It wasn't specifically designed for lithium but if willing to manually push the boost button on the optional charge wizard pendant it will work really well. Been doing that for years for generator charging. If I remember right it will stay in boost mode outputting 14.4 volts for 4 hours.
Hola buenas tardes favor si alguien me puede ayudar con la configuración del controlador ML4860N15; Tengo panel en 96 V de entrada, BB VRL de 48 V 100 AH
Yes, for a 24V battery system the max solar wattage doubles to 1100W so that means it will still max out at 40 amps on the charge output www.srnesolar.com/wp-content/uploads/2020/11/MPPT-Solar-Charge-Controller-ML2420-Instructions.pdf
Hi, I have this same model and I wonder how do you monitor the dod? Does it mean if the battery icon shows 2 bars then I’ve used up 50% of the battery? Thanks in advance.
Yes, but there is also a screen you can access that will show the battery DOD in percentage but keep in mind these figures can be inaccurate since they are just based solely on voltage and that can fluctuate based on the load the battery is under. I'd look at it as a rough guide to the state of charge. To get an accurate figure you'd need to install a more sophisticated battery monitor system that uses a shunt to keep track of the amperage in and out of the batteries.
I recently bought the same charge controller in 20 amp. While it is charging the first light on the box lights on and off. Is that how it is supposed to be or does it have to be a constant light?
Page 11 of the manual tells you what the LED indicators mean. How fast they flash means different things www.srnesolar.com/wp-content/uploads/2020/11/MPPT-Solar-Charge-Controller-ML2420-Instructions.pdf
It says in the specifications user mode battery parameters 9-17V www.srnesolar.com/wp-content/uploads/2020/11/MPPT-Solar-Charge-Controller-ML2420-Specification.pdf But I haven't tested it.

Sorry, I'm not sure what you're asking.
Hola buenas tardes favor si alguien me puede ayudar con la configuración del controlador ML4860N15; Tengo panel en 96 V de entrada, BB VRL de 48 V 100 AH
have you tried to upgrade this to 24v with morethan 550w charging energy? can it handle 20a charging on 24v?
Yes, for a 24V battery system the max solar wattage doubles to 1100W so that means it will still max out at 40 amps on the charge output www.srnesolar.com/wp-content/uploads/2020/11/MPPT-Solar-Charge-Controller-ML2420-Instructions.pdf
Hi, I have this same model and I wonder how do you monitor the dod? Does it mean if the battery icon shows 2 bars then I’ve used up 50% of the battery? Thanks in advance.
Yes, but there is also a screen you can access that will show the battery DOD in percentage but keep in mind these figures can be inaccurate since they are just based solely on voltage and that can fluctuate based on the load the battery is under. I'd look at it as a rough guide to the state of charge. To get an accurate figure you'd need to install a more sophisticated battery monitor system that uses a shunt to keep track of the amperage in and out of the batteries.
@@LoveYourRV Thanks for responding! We’re totally clueless and this really helps.
I recently bought the same charge controller in 20 amp. While it is charging the first light on the box lights on and off. Is that how it is supposed to be or does it have to be a constant light?
Page 11 of the manual tells you what the LED indicators mean. How fast they flash means different things www.srnesolar.com/wp-content/uploads/2020/11/MPPT-Solar-Charge-Controller-ML2420-Instructions.pdf
Hello,
CAN THE 4S LITHIUM ION BATTERY BE CHARGED WITH THIS DEVICE? VOLTAGE 16.8. THANK YOU FOR THE INFORMATION.
Sorry but I don't have that type of battery to test it on. But here is the manufacture contact information www.srnesolar.com/contact-us
@@LoveYourRV Tahnk you. CAN WE ADJUST 16.8 V WITH USER MODE?
It says in the specifications user mode battery parameters 9-17V www.srnesolar.com/wp-content/uploads/2020/11/MPPT-Solar-Charge-Controller-ML2420-Specification.pdf But I haven't tested it.
@@LoveYourRV Ohh ML2420-Specification thank you :)
