Victron Energy SmartSolar MPPT 75V 15 amp 12/24-Volt Solar Charge Controller

Price at Amazon is super costly. Bought it from Solar shop Aeroville. Mppt75 10 with BT. Not able to open. Fully potted

Solar energy is a great way to have back-up power for your home or for your RV. Solar isn't super complicated, but there are a lot of things you need to know to make the best purchases. Solar charges (like the Victron) come in both PWM and MPPT. PWM are significantly less expensive, but may fit your needs. MPPT is a better option, and this very affordable Victron unit is a fantastic entry-level charge controller. It's 75/15 name refers to the maximum volts it will accept/use from your solar array, and the 15 amps it can accept/use. The Victron Smart Solar 75/15 can handle up to 300 watts of solar panels wired in series or parallel. In series, that's about 68 volts max, well within tolerances, or 16.5 amps max which will be capped at 15 amps. Truth is, except for perfect sun and panel angle, you're not likely to hit the 16.5 amps. Still, that's not bad! A great part of the Victron 75/15 design is that it has bluetooth built in, so don't need to shell out extra for a dongle. Note: if you want this, look for the "Smart Solar," if it doesn't say this, you'll need a dongle. The size of this unit is just excellent; I bought it for my DIY powerstation. It works great, giving me nearly the full 100 watts from my Renogy solar panels under ideal conditions. For the money (about $65 at the time of purchase) it's simple enough for the beginners, or strong enough to manage a modest RV. Cons: It uses small, flat-head screws, so you'll need a small "pocket" screwdriver to make the connections. The input for the wires is pretty small. I had a ferrule kit, so I was able to insert 12 AWG with no trouble. I don't know how you'd easily get 10 AWG (somewhat standard for solar) but what I had worked and I'm happy.

Great solar mppt

Va genial,te informa en todo momento y con información en tiempo real de la gestión de carga gracias a su conexión bluetooth, está muy bien de tamaño porque no ocupa mucho espacio, fácil de usar y muy completo.

ممتاز والتحكم بالجوال بالتطبيق غن طريق البلوتوث

With only 175w of solar panels on my "Solar Shed", I've never wanted it to offset my normal house mains supply, but I did add 816Ah of flooded lead acid battery capacity and a 2.5 Kw mains inverter so that I could keep the fridge, freezer and some LED lights going for a couple of days if we ever get power cuts. On the weeks when the power is solid, I use the "Solar Shed" to do a couple of washing machine loads, and run the electric lawnmower. This has all worked fine in the summer but the old PWM controller that arrived with the panels, was struggling in the winter. So when it also developed an intermittent fault last week, I started researching a better replacement. The Victron unit is far superior in every respect. Firstly, it harvests about 15% more power at low light conditions than the PWM unit could, and secondly it is amazingly configurable, via its Bluetooth driven link with an App on your smartphone (see pics). I was particularly pleased to see that it can automatically run an equalisation charge at a voltage of your choice for a defined period after a user configurable period of days that can be over some weeks or months. It also allows you to just run one manually - ideal on a nice sunny day when the batteries are already "Floating" and you just want to get the Specific Gravities of all 18 cells to be nice and uniform. I have three top tips for you if you want to invest in this top quality controller:- A). Read the manual and pay careful attention to polarities when you connect the load, battery and PV positives and negatives. The battery is different, see.. B). When you download the APP and run it for the first time, it will automatically request access to Bluetooth itself and "find" the controller - Pass-Code is "000000" (Six Zeroes) C). If you don't want the load to be "Permanently on" (The default), then you will have to install and run the App, go to "Settings" (The wee Cog) and change it to "Permanently off".
