Victron Energy BlueSolar MPPT 100V 30 amp 12/24-Volt Solar Charge Controller

It's victron, functions really well. Wish they had a way to set the final charge voltage as it only charges my lifepo4 cells to 13.6.

It’s a Victron what else is there to say.

I like that the connection process is very simple, and the instructions for the device are very clear. BE AWARE that you MUST connect the Bluetooth dongle (sold separately) in order to use the VictronConnect app for your phone. You can connect solar panels in series, up to the max input voltage of 100V. Higher voltages produce more output Amps and Watts at the battery output. Series-wired panels will output the Amps of ONE panel at the SUM of their output voltage. You can connect sets of panels in parallel to get more output current (and Wattage) but in parallel, the Amps add up, so don't overdo it. Aim for about 20-25 Amps max, to avoid overloading the device. I'm running this with 3 pairs of 100W panels in parallel and it works perfectly. for charging 2 or more 100Ah LiFePO4 batteries.

I bought this to replace another brand which made a mockery of its own MPPT claim: I could barely get 200 watts to my batteries from a 600 watt array of six panels for a 24 volt system. Then that "controller" failed entirely after about four months. Check my other reviews if you want to see what's up with that one. Learn from my mistakes.There are no real features with this unit, but it does a real good job at what it's supposed to do: get you maximum power to recharge your array well-regulated without burning up your equipment with excessively high voltages. With this unit on the otherwise same setup, I have seen up to 515 watts in late April not anywhere near the highest sun of the year. It also does remarkably well in cloudy but bright skies. I don't have the Bluetooth model and don't care really since my batteries do tell me what's going on via their Blueteeth connections.I downloaded the lengthy owner's manual and read it well because it was not intuitive at all how to set up the controller or to decipher the status lights. Take the time and do this BEFORE just hooking it in and using so you get it right for your system. I had to be sure I set the switches properly for my LiFePO4 batteries and system voltage limits, etc., and not fry thousands of dollars of batteries by not being careful. My overall rating is tempered only by the fact this controller's only been in service for five months.

This Victron MPPT handles the wiring better for thicker wiring sizes. Performance wise its excellent.

This product failed after almost 5 months of use. It seemed to work well until then. Failure was evident in recognizing solar panel input. A backup MPPT I had was then installed, and solar charging was returned. I asked Amazon for a replacement, but they directed me to Victron. Victron's response was for me to contact Amazon for a solution. At this point, I don't know where I stand - other than being out about $250. I now see reviews on YouTube indicating this MPPT has been a problem. I thought the "quality and service" of Victron, eventhough their cost is higher than others, would be the best product to use. Now it appears that less expensive versions of similar hardware are a better choice. I do not recommend Victron's customer support.

Great products, as with any solar systems/components make sure you have proper(large enough)wire size for the system and that all of your connections are tight throughout the entire system. Better to have a little larger wire than you need than too small. The components will thank you so will you pocket book!Health & Wealth!

Goes into fault too often needing reset. Loses blue tooth connection consistently. Had dead batteries on multiple occasions with this device.
