    Sorry i have not used the 7210a for sometime. Utube videos are pretty good. You do need to set the battery parameters. It did do the cv to cc functions correctly. I think charge rate was also (amps ) was also adjustable. Themeter readings were accurate. Charging from a battery would need to watch that 12v. Battery is not drained. This would need anothee device to shut iff when battery drops. Not good if bike runs but truck won't start.
    seems a very good solution. More efficient than other charging methods andhighly adaptable. Justnot good enough for solar.

    Do you have any pointers for using the mpt-7210a? I usually refer folks to this thread if they want to learn tips to wire a car's 12vdc output to their battery rather than using a charger. Not strictly solar related and I know the genasun is better but that sort of flexibility is really useful

    Appreciate the likes. Comments appreciated. Suggestions welcomed. The more interest shown, the more motivation to post share and develop this.

    What i like about my bike. Comfort. Wind and rain protection. Aero faster speed and more range. Self charging. Less time and safer charging outside. No electric cords or chargers needed.

    Returned the lousy cynergy 120 volt panel. Got a 100 watt renogy. Now getting 1.5 amps cjarge rate for 52volt battery through henasun controller. Far better than.6 amps.

    Rebuilt fairing lighter weight stronger. Replaced running boards. Modifying for more aero. Looking like 200 mile range with 2 batteries at 20 mph plus.. (33 ah) more road testing and alterations.

    The 120watt panel i put on the fairing increased x rag. The 160watt panel gave 2 amp charge the 120 watt is only producing .6 amps. Probably it is operating at too liw of range for controller to be efficient. Had to rebuild fairing to take weght of panel. And much lightee Now have to modify to reduce drag created by panel. At these levels the system is not effective. Yet. With both oanels running, performance is awesome.

    The simple prototype fairing that works well. Noted i never posted ot before.

    The drag from panels could easily exceed the production. Using the panel to reduce drag would be optimal. Buy panels that can be mounted in a helpful aero design. I have fewer options in having only two wheels. Your trikes should have far more options. I am really happy with the performance and appearance of the fairing. Far more comfortable in cold mornings. Drier when rains start. My cost for this fairing was under 5 dollars.

    With fairing i hit 38, mph when speedo quit working still accelerating Undoubtedly the fairing works. I am mounting my panel to this fairing as original plans. With this kind of economy i do not need anything better than 120 watts.
    next is tailsock and aero panniers. And canopy. Internet connection is bad. Pictures later.

    Messed up another pcture. But framework under aluminum sheet is cut 3/4 inch fence boards. Bungee holds it tight to bars.

ID:	92789 Amazing 15 miles over 20 mph avg. Some atop and go. Fairly flat. 12.5 watt hpurs per mile. I thought something wrong. But confirmed. I was not expecting this.

    Sound interesting, pictures would be great.

    I definitely notice that my trike has much greater wind drag than my wife's.
    I installed the Genasun on her trike last Friday and we went out for a test this weekend. With only a 100W panel feeding her system she was about 5% lower charge than me at the end of a 40 mile ride, wings folded except when stopped.

    I've been considering some kind of fairing just don't know how I could do it with the solar panel frame.

    Too old play contortionist trying to climb in.

    While waiting for 120 watt smaller panel which should supply every day needs, i finished a project that has been sitting in a hidden corner. A fairing. The result was pretty good. Really notice at higher speeds aero braking is poor. The size is very close to what i need for panel.
    winter is coming. Need to get windshield and convertible top finished.
    Will be interesting to see if the economy improves at higher speeds. My bbs02 is pushing above 35mph. That was slight uphill with headwind. Far better than expected.
    when better connection will load picture.

    Just like the e bike mfrs claiming excessive range, a solar set up is difficult to judge. With far more variables. For range, really need to ride at bicycle speeds. Fast electric bike is not possible without long recharge times. Cost and weight is similar to an extra battery, but no down time waiting to charge or finding place to charge.
    in the real world of everyday driving, actual range of 13 ah 52 volt is pretty much doubled. 10 watt hours per mile is a pretty good solar boost. Still need ten from battery. With consideration that you are charging while driving, charging time is no longer a consideration. Almost three weeks of panel i have plugged into wall once. Always a 65% + battery.
    most comments have to do with how large and odd the size looks. (I wannt even more!) No comments that i judge to be negative. Maybe i do not listen!.
