Thought some others might be interested in how a particular product performed.
is Tracer 2215BN with their MT50 remote
control & display. Didn't receive the remote battery
temperature sensor yet, or the serial
to USB cable which
could let a PC control or display the status.
Panel is ALEKO 24V (nominal) 140W panel 55" x 27" x 1 3/8" approx
Overall they all seem pretty good, only tested in the yard. Some recommend flexible panels
for a boat, this is rigid panel with tempered glass cover sheet. It's going on a rigid bimini
3:00PM afternoon sun, about 70 degrees F according to the controller
In order to get the most out of the panel, a 12V coffee maker was hooked up in parallel with a 110ah marine battery
. The MPPT charger
appears to be doing its job as shown in the first picture: the PV panel is measured at 41.1Volts and 2.8amps of power going in, and the output at the battery is 14.4Volts and 8.1amps. I confirmed the voltages with an ohm meter at the panel input and battery output. I did not confirm the current
because my clamp meter is on the fritz, and I didn't want to mess with all of the wires to do it with my ohm meter. Not like some magazine is paying me, but I digress.
By manually tilting the panel in one hand, with the other hand taking the photo
, the max power observed was about 124W. That is pretty good for a 140W nominal panel in less than perfect sun as far as I know.
To early to know how reliable the equipment
will be, or whether I should have chosen a flexible panel.
The MPPT controller has programmable voltages, but I haven't changed anything other than set battery type to flooded and 110ah.
The MPPT controller and mt50 where $134 delivered, and the panel was $199. Both were from that * bay site from different sellers. I'll be getting the temp sensor, and USB cable for $10 from another.
Thanks again to this forum for providing lots of help. I'll try to answer any questions here, and update after the season. By the way, I'm not affiliated with any company or reseller for these products and am not getting paid or free stuff.
