BlueSolar MPPT Solar Charge Controller - MPPT Charge Controller for Solar Panels - 75V 10 amp 12/24-Volt

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.

Bluetooth app works well. solid unit. works to specification

Why did you choose this product over others?: Quality

Does exactly what it suppose to. No issues with this controller.

Don’t buy this. It has no Bluetooth , despite the name. Very misleading and the units are in every other way identical. Also very misleading is the claim it has Bluetooth, when in fact you need to buy a £32 dongle. Get the SmartSolar version instead. Same price, comes with Bluetooth. I didn’t take it out of its box until past the 30 days return window , otherwise I would have swapped.

Using this on two 100 watt panels in series in the summer and parallel in the winter. My only criticism is Victron only include presets for the batteries they make so no flooded lead acid.

The controller charges, but we don't know anything more without a Bluetooth device that can be purchased for almost the same price as the controller. For that price, it's a bit excessive not to have visibility into the charging power and the battery charge level.

Good

Totalement silencieux pas de ventilateur, fonctionne à merveille.

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.

I bought this to add some solar panels to my LiFePo4 batteries, it works well and with the optional bluetooth adaptor it gives a lot of useful information. I will be going off grid soon when I move onto my block of land permanently and this is a good start to dip my toes in before I go totally off grid.

Wie gewohnt von Victron... Zuverlässige Qualität, Einfach ohne Schnickschnack

Ho acquistato il regolatore per poter usare un pannello solare amorfo che ha una tensione di uscita che arriva a 70 V, quindi incompatibile con i comuni regolatori PWM economici. Rispetto a questi ultimi è all'apparenza molto più solido (pesa almeno il doppio) e, si spera, anche più affidabile e duraturo. Il collegamento è semplice e standard per questo tipo di dispositivi, le istruzioni sono chiare e ben scritte, anche se non in italiano. Consigliato se si vogliono usare pannelli solari amorfi, visto che da varie ricerche in rete è l'unico modello che ho trovato che li supporta. PRO: Molto solido all'apparenza, supporta una tensione in ingresso fino a 75 V. CONTRO: Istruzioni in 6 lingue, ma non in italiano.
