Victron Energy BlueSolar MPPT Solar Charge Controller - Charge Controllers for Solar Panels - 75V, 15 amp, 12/24-Volt

This is an excellent Solar Charge Controller, but to configure it, you need to also buy the separate Bluetooth adapter. Once I had both in hand, I set them up to charge my RV's house battery with an older pair of 12-volt solar panels, wired in parallel. Using the Victron app, I discovered the panel's output voltage was not high enough to charge the batteries, even though the controller's "Bulk" LED was lit on the controller (the controller requires the charging source voltage exceed the battery voltage by at least 5 volts, and in my test case both voltages were about 12.5 volts). After re-wiring the panels in series, I was able to see actual charging happening as the panel voltage exceeded the battery voltage by more than the threshold required (the displayed panel voltage was in excess of 20 volts). After a few hours, I observed the controller's LEDs transitioning from Bulk to Absorption to Float. It was very satisfying seeing the MPPT function at work as the input voltage and amperage were adjusted to supply optimum charge voltage and current to the battery. There is some confusion as to whether this controller has built-in Bluetooth and in fact it does not. Having to buy an additional Biuetooth adapter is annoying to some who are familiar with Victron's other range of devices that have it built in (and I was one of the annoyed people). The aggravation is intensified once it's understood that only a couple of parameters can be controlled except using Bluetooth and the Victon app. Some of the competition also sells their Bluetooth dongles as an extra cost device, for example, the Renogy Rover Charge Controller (I know because I own one). In the case of the Rover, all functions can be configured on the unit using the buttons and seeing what is happening on the built-in LCD display. Configuring by way of the buttons is a bit tedious, though. Having the Bluetooth not built in is a security advantage in that once configuration is complete and the Bluetooth dongle is removed, no unauthorized changes can be make to the setup. Also, the dongle can be used for any number of similar devices. The unit is compact in size and has no user interface, except through the app. It seems well built with an attractive Victron-specific industrial design. I do question its lack of a heat sink on its backside; time will tell if that's a liability. By skipping that and removing the Bluetooth function from the controller, Victron is able to sell this device at a reasonable price. All in all, I'm very happy with my purchase.

This controller almost seems to pull energy from clouds. I tried two Tracer Series MPPT controllers (10A RN and 20A BN series). They are good, but compared to this controller they are slow catching up with the rapidly changing cloud conditions in the Pacific North West near the Canadian border. Quick rundown on likes: - It rapidly finds the mpp, and seems to build local profiles to swap back to in rapidly changing conditions (from direct sun to dark rain and in the middle). - In a side by side test, this controller reliably harvests at least +10% more energy from my Lensun 80W 12V panels than either of my Tracer controllers. - It has a built in battery charging profiles you can select by dial - including one for LiFePO4 batteries. - The documentaiton is clear and in English. - The firmware upgrades installed quickly and flawlessly. Additional things that put this controller way over the top for me: - Victron ToolKit app for the complete listing of blink codes to let you know what program the controller is running on. The information is in the manual, but the animated app gave me great peace of mind to know I wasn't about to do damage to my LFP battery bank. (The setting dial has no indication of what setting it's turned to, so blink codes are the only way to know for sure.) It was handy to have the cable calculator to confirm wire sizes, run lengths and voltage loss. - The BlueTooth dongle. Not required since the lights on the controller clearly tell you if you're in blulk, absorption, or float mode. However if you're a freak/geek like me and want to see settings in detail, have peace of mind about your battery bank while the controller is in action, and monitor performance? It's well worth the price of admission.

Excellent quality, typical of Victron. I'm fed up with trying to save money on cheaper solar gear (where it matters, like here) and only use Victron. The stuff just works. The app just works. You plug it in and it works. The instructions you receive are legible and correct and (shocking!) they actually pertain to the item you bought, not the one 3 versions ago that is totally different. This charge controller is excellent and dependable. It just works.

Wish it had been clear about it needing the adapter to use the Bluetooth feature. So wasn't pleased about that. The unit however, was top notch. Worked great and once I purchased the bluetooth add on was the most impressive iv ever used. The software is superb. Would have liked to have known I needed the adapter from the start. That's my only issue. It is the best controller iv ever used.

Excellent value for a true mppt charge controller. Perfect pairing for my 2 100 watt panels wired in series I recommend getting the Victron bluetooth adapter for changing parameters and fine tuning things like streetlight function. Unit has many options for battery types, ability to charge, float, equalize if needed. Full adjustable charging parameters. First two days it was able to charge my battery to the first time in months. Much easier than using a cheap, knockoff “mppt” controller. Solid unit that doesn’t need fans to keep cool, so it’s quiet while doing it’s job.

I own several Victron products along with this charge controller. they all worked right out of the box, just like intended, blue tooth connection was quick and worked flawlessly. can't say enough about Victron products.. Yes they are expensive but worth every cent.

Totalement silencieux pas de ventilateur, fonctionne à merveille.

Item was good & delivered on time

Have tried a few other types of controllers for solar charging to caravan and after a bit of faffing about and not gaining sufficient charge to off grid sites went for one of these. There are different variations to match your needs but these bad boys rinse every particle of energy being produced and tuck it into your battery for later use. The Bluetooth has its benefits and give you history of charge/solar panel captivation and +- battery charge levels. Its a bit of overkill but did buy a second for a spring project for the shed.

Top Gerät, ist mein vierter

très bon produit mais il manque le Bluetooth pour pouvoir gérer via l'application
