Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - Charge Controllers for Solar Panels - 75V, 10 amp, 12/24-Volt

Received controller yesterday and installed yesterday. It works as described, very nice. Bluetooth works very nice, the available customizable functions are enough for my needs. For the money and what you get, i will never buy another $20 etc. budget controller again. This one is the 75/10 and i did not know the 75/15 was only a few dollars more or i would have bought that one, why not. I use these as battery maintainers on my autos, big boy toys etc., I have been through allot of $20 budget controller that i have no customizable functions, no more of that. I will buy a few of these i think. If i had to give a negative it would be the Bluetooth range you have to be pretty much right next to it, at least that's what i am finding. I have other Bluetooth devices that i get much farther ranges on.

I have two of these connected to lead-acid deep-cycle batteries. One drives a remote bird-house camera and one powers a pump in a bird bath. They were easy to set up and the instructions are clear. They have enormous programmability. The phone app is great for checking on the battery performance, solar power level, load, etc. There are a couple of features I wish it had. One is more pre-programmed battery types. They offer a few basic battery types and a custom program of gazillions of charging parameters for experts. I'm an electrical engineer and could get out the data sheet for my specific battery and program all the parameters, but what a hassle, and what if I make a mistake? It would be nice to have a few more standard lead-acid battery types in the menu. The unit has a streetlight function for turning on a light at night, but I want a general purpose timer that turns on the load in the day. That would be a small amount of software for Victron to add to the unit and the application. I want our birdbath to run only during the day. I could have used a smaller solar panel and smaller battery if this unit had a timer feature. This unit keeps a history of solar power generated and load power consumed that goes back at least a few weeks. I haven't looked to see how far back it goes, but it's interesting and useful to see how the panels are doing, or if the load is drawing unexpected power. It was also useful to see if my calculations were correct.

I needed to light a tree in less-than-ideal solar conditions using solar power only (charging a 12V battery). I first tried a 12V solar panel with a PWM controller, but it could not keep the battery charged. I found I needed a more sophisticated MPPT controller, so I purchased this Victron Energy SmartSolar MPPT 75V, 10 amp Solar Charge Controller to replace the PWM controller. It worked with the 12V panel OK, but still not good enough to keep the battery voltage in the "safe" voltage drain zone in the poor and varying sun conditions I had (Winter weather, often in low-angle tree shadow). The SmartSolar MPPT controller documentation recommended a 24V solar panel for a 12V battery. I changed to a 24V panel, and it worked great! Using daily measurements from the MPPT controller (via the Bluetooth VictronConnect app), I found that the 24V panel's voltage kept the PV input voltage often at over 20V even on a cloudy day and/or in the shade of trees. The SmartSolar controller converted the extra voltage to the charging power I needed. Keeps my battery charged at above-minimum voltages even on snowy days! Just what I was hoping for! See my chart for my testing results.

I have three Victron Energy solar charge controllers of different sizes. I love them all and personally think they are the best. They perform flawlessly and are extremely efficient. The controllers all have the same configuration interface per Bluetooth with the Victron Energy App on iPhone/Android. I can set up fully customized charging profiles easily and can see the performance at a glance. The controller is small and robust, weather proof and is a great value for its performance and price. I will say that if you attempt to get any support from Victron Energy, forget it. You are out of luck and have to go to the dealers for help. Please check who the dealer is before you buy so you have someplace to turn to for support if needed. Because of the support aspect, I give this controller 4 stars. I wish there was a better support system for customers.

This Victron charge controller is a good choice for small projects such as keeping a vehicle or sump pump battery charged from a 25 Watt (or larger) solar panel. Ability to tailor parameters and monitor performance with a Bluetooth connection is a plus. The unit is dust and moisture resistant when mounted with the terminals facing down. As expected the MPPT buck/boost circuitry assures your battery gets the most possible charge given variable solar exposure. The Victron is more expensive than some, but is brand offers better than average quality and features. It makes sense to invest in a good quality controller to get maximum use and lifespan from your expensive batteries.

Vergi dahil olup olmadığına dikkat edin, bir de smartsolar mı bluesolar mı alıyorsunuz ona dikkat edin. Bluetooth üzerinden ayar yapmak için smartsolar modeli gerekli.

¡Todo como se describe, buena calidad, volvería a comprar!

Installation simple et paramétrage rapide en Bluetooth, très bon produit, je l'utilise pour charger une batterie LifePo4, fonctionne très bien

Pros: Works great for a small solar setup Phone app for setup and monitoring is amazing Easy connection Con: Wire terminals could be larger but work fine for wire size recommended
