Victron EnergyBlueSolar MPPT Solar Charge Controller - Charge Controllers for Solar Panels - 100V, 30 amp, 12/24-Volt

This solar controller work so much better than the furrion controller that it replaced. Furrion was working fine, how didn't charge my lithium batteries well even though it was set for lithium. Also the Bluetooth works very well an allows me to see status and history anywhere in my camper. Furrion only worked if I was outside pretty much right next to it.

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.

Its victron. It works

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.

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.

I got this for charging a 24 V battery from 400 W of solar panels (74Voc, 60Vmpp). But I ended up changing my design so that it's charging from 800 W of solar panels (parallel, so the voltage is the same). That puts it right at the current limi of 30At. But it never really gets hot. It just gets warm. It seems to be very efficient. I mounted mine to a 1/8" thick slab of aluminum, which probably helps with the cooling a little bit.

No blue tooth you have to purchase interface which is expensive relative the price of this charger. No load monitoring without another expensive purchase. Just a very basic 30a mppt charger. Much better mppt chargers for the same price with bluetooth and load monitoring built in. My return window has passed so I am unable to return it.

Love it
