Long range FPV, you need directional antenna's, a lower frequency, looks like he is using 1.2Ghz band. 600mW+ transmitter, although you can get decent range by using decent antenna's. Bonus if you have a diversity receiver to utilize multiple antenna types. Tracking is even better. I can get 2KM with good signal on 5.8GHz with directional patch / helical antenna's and a 600mW transmitter with cloverleaf.

@Mafish19957 жыл бұрын
Hey, thats exacly why do you need MPPT, in direct sunlight , at perfect angle on a sunny day you will get probably 95+% of your panels potential if you connect it directly to power system, but on a clouudy or smoky day, or even when you fly so just part of panels is exposed to sun, the MPPT can boost your power up a lot, and i mean really alot. Also your power meter is avaraging reading when it displays it so its n its not a good way to measure power. MPPTs work with usually with more than 10kHz control loop so its catching all the liitle power spikes and pushes most of it into the battery no matter how many cells it has . Keep up the good work, one of the most interesting series on YT right now. cheers!

The real benefit of a charge controller or a standard buck/boost board is the ability to charge the battery even when the solar cells aren't above battery voltage. You were correct in finding they do have a penalty for peak power, but I think that it may more than outweigh it by allowing you to use power all the time. However if you're always above battery voltage it is a moot point. Awesome video! You got me into 100w led chips, and i'm loving it!

Advice from a scientist in atmospheric physics: In case you will meet haze, etc. during future flights: Climb as fast fast you can, since these haze particles (aerosols) are confined in the so-called planetary boundary layer (not exceeding height of thermals). Just climb and climb and your plane will gain performance, once out of this hazy stuff. And get rid of this heavy Lipo. There are numerous RC planes around with PURE solar cell operation !

Usually when a plane tucks and speeds up in a dive, it's indicating that it's tail heavy (and is thus trimmed to provide positive lift with the horizontal stab, instead of more usual negative lift). For max efficiency you might want it little tail heavy, but have to be aware of that effect in a dive, or just avoid dives all together. Vector doesn't choose to descend at low amps. It's actually running the throttle at no less than cruise throttle position, but because it's descending it unloads the prop which causes the amps to drop below what you'd normally see for cruise. BTW, Vector will display watts. Just add it to the OSD.
@dadbrad8526 жыл бұрын
When a plane noses down with an increase in speed (dives steeper on it's own) that plane is in a tail heavy condition.

The backside of the cells should not be covered for the most part of it to improve cooling.

@wsc1127827 жыл бұрын
The way you were trying to measure efficiency at about 9:00 in the video is sorta problematic. You've got to measure both input and output. In other words, with the MPPT in the circuit, you need a power meter between the panels and MPPT, and another power meter between the MPPT and the battery. You would calculate efficiency as: output divided by input. For example: 100 watts coming out of the panels vs 93 watts coming out of the MPPT = 93% efficiency. You would then repeat that measurement for each different kind of controller (the two MMPTs and the PWM). That's the only way you're ever going to figure out which charger is the most efficient. Hope that helps, awesome vid.
@GaryVolts7 жыл бұрын
MPPT's have their place in terrestrial solar power systems but they aren't the best solution here. They're useful when you have arbitrarily selected panel and battery voltages but for a custom system the elements can be selected to match so the controller is just extra weight on top of the small losses to thermal systems inside the electronics.
@frank1244447 жыл бұрын
not enterly true. since the efficiency of the solar panals varry with both the amount of light and the resistance of the load (*spectrum of the light also matters). So the most efficient setting depends on these 2 variables. the amount of sunlight wont always be the same due too many obvious reasons. but the load resistance also varies. *eg: how full is the battery charged, what is the discarge rate, overall temperature potential out of spec solar panel. so aslong the efficiency/consistency gained from the controler is more that the power needed to lift the weight one should use it. wsc112782 for efficiency you indeed always NEED to mesure input and out put. otherwise you're just measuring raw power with unknown variables/changes. have said that. since thats said rctestflight might want to invest in a cheap LUX meter to make setup comparisons more easy and fair.

I'm not sure if this applies, but I used to make custom battery powered remote unattended data loggers. I would switch in a custom boost at the end of the discharge and gain a few more minutes of run time without it eating up more than it saved. I traded extra voltage by discharging the battery a little more than it normally would run my equipment. You have to test if it's worth the weight and a possibly shorter battery life for it. I really enjoy watching your engineering.

i know the charge rate in watts is important. but if you charge without voltage protection the max voltage of the cells must be the max charging voltage. another thing is if the solar voltage is lower as you battery you wont charge. ok this is obvious but what i wil say is, your mttp charger might be able to boost charge so it could use a lower voltage as input to get a higher voltage output so you get still power. unfortunaly most mttp are buck converter type charger and they go in a pwm mode if the input voltage is to low and stops about 2v difference. what you need is a boost-buck converter with mttp tracking

I plan to test a few more, but it's by no means a certainty that MPPT is best. It's certainly not super important for my application.
