This is my second MPPT 75/15 and it replaces a now defunct controller, not a Victron product. My first 75/15 controls my solar panels and this new one will control two more. Installing the product was straight forward and the instructions clear. The placement of the power source is clear and unambiguous. The Bluetooth feature is a plus.

Excellent Product

The service from 12volt Planet was excellent as is the norm, the controller arrived well packed and within the agreed time scale. This controller replaced a PWM unit which has worked well but only in full sun. The controller was easy to fit and program via the app, and the access via Bluetooth provides a substantial amount of information. Fitting this unit was a why had I not changed to the Victron MPPT unit sooner as the solar panel now provides 3-4amp output even on a cloudy bright day.

Excellent service

Excellent service. Very helpful in supplying exactly what i needed. Helped me with set up to make sure i had done everything correct. Very impressed and so nice to be able to speak to a person. Product was so easy to fit and working well. Would use 12 voltplanet again

I purchased a couple 100W Renogy panels for our travel trailer as dry camping opens up a lot of sites for us and I dont like firing up the generator unless I have to. The panels are deployed on folding stands which is really the only way to get them in the sun in the wooded campgrounds we frequent. I used them the first weekend with the PWM controller that came with the kit. It blinked nicely at me, but even with a voltmeter added to our control panel inside the camper there wasn't really a way to see what was going on. I started looking at adding monitors with shunts, but things start getting rather involved for my particular setup. At home in the off-season the camper is covered and plugged into shore power to keep the batteries up. I realized a few things.

The panels are deployed on folding stands which is really the only way to get them in the sun in the wooded campgrounds we frequent. I used them the first weekend with the PWM controller that came with the kit. It blinked nicely at me, but even with a voltmeter added to our control panel inside the camper there wasn't really a way to see what was going on. I started looking at adding monitors with shunts, but things start getting rather involved for my particular setup. At home in the off-season the camper is covered and plugged into shore power to keep the batteries up. I realized a few things. First, Im paying for electricity to charge the batteries when I have two solar panels in a box. Second, the on-board inverter/charger is OK for maintaining batteries, but really lacks the ability to keep them at a full charge as they hover around 13.4-13.6 volts regardless of battery condition and with no temperature compensation. Third, to charge the batteries requires the battery kill switch to be on, meaning Im also powering gas and carbon monoxide detectors and who knows what other parasitic loads in the camper. Not a monetary issue but things without power on them cant cause unforeseen issues. I had originally fallen prey to the argument that youre better off buying another panel vs. paying for an MPPT controller. That works on paper but I realized that Ill set out 2 panels, but I will never set out 3 or 4. That meant the Victron SmartSolar 75/15 would work nicely and the cost was within my threshold of pain. The need for a separate monitor was also negated. Installation was easy as I was just replacing the PWM controller. My setup is a couple of group 24 lead acid deep cycle batteries with around 160ah. Power is brought into the storage bay of my travel trailer with 4/0 wiring where it splits off to a 3000/6000 pure sine inverter. The Victron is wired into the 4/0 cables which are only about 18 away with 10 gauge cabling. The Zamp plug that came with the camper was replaced with a 10 gauge wire unit, and the 20 of Renogy cable going to the panels is 10 gauge. The storage bay isnt heated so its within a few degrees of the batteries which are on the tongue. After doing an update the unit automatically selected 12v and the default charge setting was for deep cycle gel batteries. I was initially a little worried that there wasnt a specific setting for lead acid batteries but the parameters of this option are apparently fine from what I can gather. Equalization is off by default. After installation I zipped the camper cover back up all I have to do now is walk by and log in to see whats going on, no need to unzip/unlock or interrupt my nap when were actually camping to check our state of charge. The attached screenshots were for the first few days. Im only using one 100W panel as I felt this would be sufficient. The battery bank was at 90% charge the first day (see handy chart) and I was pleased to see that it got fully charged but concerned that my 100W panel was only putting out 35W in full sun. A 100W panel is going to max out somewhere around 70W in the northern hemisphere on the best day in the summer and this was in January, the lowest amount of available solar energy (insolation) of the year. The following days were even worse until I understood that Pmax isnt your panels peak wattage, its the peak that the controller will draw from the panel as it manipulates current and voltage to get what it wants. Youre not going to see a Pmax that resembles the published output of your panels unless you have a big load on them (or drained batteries) and maybe not then. This is a laymans explanation, but if it keeps you from thinking you have a bad panel or connection its worth the keystrokes. Of the following three January days the first was sunny, the next was cloudy and the next was rain. The Victron doesnt care, it still pulled plenty of voltage out of the panel and quickly went into float. Its like a honey badger. Perhaps more interesting will be what happens when a live load is applied (such as when were actually camping and using power). Toggling the electric tongue jack gets an immediate response from the controller as it ramps up to offset what youre using, then it goes back to putting the battery back to the state of charge that it wants. Comparisons between PWM and MPPT controllers are made in somewhat of a vacuum, you can spend hours reading them. In the real world of RV use the MPPT probably offers more advantages than published. On cloudy and rainy days MPPT wins, but though its hard to quantify it also wins when you have partial sun exposure due to your location. I love wooded/private campsites. Most examples use a sunny day with no loads and the PWM can do what the MPPT does, it just takes longer. Lets say Im fully charged by noon and at ...

If you are into the solar panels, you may need this solar charge controller. The controller has a solar panel connector or input, a battery connector , and the load connector, all complete separated from each other. . Take a look at the sketch. Anyway, the bluetooth works very well. By the way, get the controller with a bluetooth, very easy to monitor the controller, and upgrade the firmware if available. The bluetooth range is excellent. My personal weather station(PWS) has been up and running since I installed this controller without a glitch. As soon as the Sun set, the controller disconnect the battery from the solar panel, right in the morning when the Sun is up again, it reconnects the battery.

Liked this controller from the moment I took it out of the box. Has a good solid feel and looks like it's quality built. Installed it near my battery bank and close to my BMV 712 battery monitor. Once hooked up firmware updates took over but once finished I was surprised at how well the controller and monitor shared information. If battery monitor has temp sensor battery charge rate is temp compensated using the shared data I am using a 160 wat portable unit so I had to maximize power harvest as much as possible. Cut the supplied, cheap, PWM controller out of the circuit then wired panels in series. Feeding over 43 volts into this controller and am charging with 90% of the panel capacity with just morning sun that hasn't reached optimum height/angle. Well worth the ... MoreLiked this controller from the moment I took it out of the box. Has a good solid feel and looks like it's quality built.

Well worth the price and the BT connectivity is priceless. A perfect mate to a BMV 712 battery monitor. I bought the 15 amp model even though the max output of my panels in series is less than 4 amps. For the slight difference in price over the 10 amp model I now have room for a larger PV array if I ever choose to upgrade.

Review of Victron Solar Charge Controller SmartSolar MPPT 75|15 Bluetooth | SCC075015060R

The Victron Solar Charge Controller, SmartSolar MPPT 75|15, has been a perfect product to get me exploring solar energy production as a newcomer. The charge controller was easy to connect into the solar circuit and the Victron Connect App was also easy enough to install on both laptop (running Linux) and Android phone. There's lots of additional support information for the product on Victron's website and across youtube.

Used this charge controller with a 175 watt panel at 12 volts. It feeds the line in. The battery out goes to a dual Nissan Leaf module hooked up in series (16 volts). The load on the charge controller goes out to a voltage regulator to step it down to 12.8 volts and out to a series of USB ports and 12 volt lighters. Programmed the charge controller to 4 volts per battery cell at a max (16 volts, 64 ah). Used the lithium ion preset adjusted slightly. On the load output I set the limit to shut off the load when the voltage on the battery gets below 12.5 volts and stay turned off until the voltage on the battery rises up to 15.85 volts. In other words, this one box has made my setup thoughtless and automatic. So in cases where my fridge or other loads drains the ... MoreUsed this charge controller with a 175 watt panel at 12 volts.

In other words, this one box has made my setup thoughtless and automatic. So in cases where my fridge or other loads drains the battery to the minimum it will turn off the battery output until it charges enough to last the night without solar adding voltage. The bluetooth part is nice just to make programming easy and gather statistics. Can't really complain about anything on the box or the functionality. It just works and includes enough options to make it seem like magic.

Victron 12/24 15amp Controller.

Unit works as expected, Victron is my go to brand for solar. Purchased to replace older style controller and to get more efficiency out of my 200w panel. Early days, but I’m seeing approx. an extra Ah compared to the replaced unit.
