I don’t know if it will harm the 200’s but my limited understanding is that it would reduce the SP200’s to a lower wattage. Its best to stick to similar volts/amps when combining in series. They don’t have to be exactly the same, I combined two Renogy 200 watt panels with my three SP200’s and am getting the full 700 watts into my AC200P even though each panel is producing less power than it could by itself. Take this advice with a grain of salt since I’m a solar rookie and am learning as I go.
The Bluetti SP200’s are rated at 20v/10a so three would be 60v. His 100 watt panel is rated at 18v/5.5amp. So my understanding is that you would add all the volts (78) and multiply it by the lowest amps (5.5) which would = 429 watts total? If so not a good choice since the Bluetti’s would be 600 watts on their own.
Getting about 70V an good full sun. As an FYI, I ordered another SP200 as Amazon had them on sale for $395 (could buy only one). I also figured out the output polarity of the other panel seems to be reversed with anything I hook to it, so not messing with it.
Bluetti is coming out in the future with an enhanced charger called the D050S. It would connect between your solar panel and the AC charging input port of your AC200. The DO50S contains a charge controller and converts the voltage to an output of 58.8 volts in order to charge through the AC input port. But…not sure if the 100 watt panel you have would warrant the cost. Don’t know the price yet but think it will be around $125 or so. If you were starting over, buying an additional SP200 would yield better results
Thanks Scott! I did just go ahead and buy another SP200. Amazon had them on sale for $395 for a single purchase (additional where the regular $499). So 4 SP200s should do what I need.
I know this question is not in this thread, but could you answer my concern about the AC200P unit being on with AC ON and just the unit itself draining 2% per hour? Seems then that the absolute max use you can get using AC then is something less than 50 hours if you running even just a light on AC.
Yes the AC200 consumes power even with no load in the on position. The large inverter and large capacity dc power regulation consume energy just being on without any electrical power output. Think of you and your body sleeping. You consume energy and burn calories just laying there but producing nothing. The larger the person the larger the calorie consumption. There is nothing wring with leaving the AC200 on and even on with the ac and dc outputs activated. But……the more you leave on, the faster your battery will discharge
Good to know. I bought it for the fact that it can run 2000W. I couldn’t find anything else that would run a coffee maker, MicroWave, and even a Hot Plate (which draws 1600+ Watts!). So it is doing the job. I have a FlashFish 300W for the small stuff.
