Re: Nicro Day-Night 2000 solar vent repair

@Toofani: I had no problems with the motor on our vent, but the multimeter showed that the solar panel had gone south. I bought a new waterproof, 2V solar cell on ebay for about $8. I had originally intended just to mount it on the top of the old vent, ugly but functional. In the end, I was to fit the new cell inside the old vent after removing the old cell and doing a little work with a dremel tool. The fan works great during the day, but it's still not operating at night. I haven't reopened it to troubleshoot as I'm currently satisfied with it running for the day. I have too many other projects. I would say, yes, if you can solder, you can replace the solar cell for much less than the cost of a new fan.

Re: Nicro Day-Night 2000 solar vent repair

Rachel-
I would guess your fan is not operating at night because there are two 1.25v cells in the battery pack, so it needs about 3 volts in order to charge them up. With one 2-volt cell, you can't charge the batteries and there's no power to run the fan at night. A 3-3.5v solar panel is probably optimum, a 4-volt probably would also work fine.

Re: Nicro Day-Night 2000 solar vent repair

For what its worth, the repairs to our vent described in my posts #42, and #46, preceding, continue to work well. Our vent spins away quite merrily during the day and continues all night and/or when there is a heavy overcast. It seems our battery is recharged enough to allow out vent to operate for about 40 hours without a good dose of sunlight. If Rachel's replacement panel is not working well for recharging, it may be that a diode is needed to prevent the back flow of power into the panel from the battery. A tiny little diode was included with our replacement panel and I did use it, which may explain our success to date. So far, the system seems to work.

FWIW...

Diode: YES! That would make a difference.

Re: Nicro Day-Night 2000 solar vent repair

@ hello sailor: Looking back at others' pictures, I believe the Nicro model I have is slightly different. It was powered by a single, rechargeable C battery. I assumed that a 2V solar panel would cut it for charging. I wouldn't rule out a simple, stupid mistake such as my putting the new battery in backwards. I was so excited that the solar cell was pushing the motor again, I wasn't paying much attention to the battery side of things. When I have a free afternoon, I'll crack it back open and have a look.

Re: Nicro Day-Night 2000 solar vent repair

Rachel, if you've just got one cell (battery) in there, yes, 2v will do it and HyLyte's pointer to the diode would be the next thing to check. Of course it is also possible that an old battery is simply shot and won't hold a charge any longer. Easiest way for you to test that would be to let it charge during the day, disconnect it late in the afternoon, test the battery voltage, and then retest the next day or a couple of days later, to see if the battery holds that charge while not connected to the solar panel.

Re: Nicro Day-Night 2000 solar vent repair

I put a new battery in when I reassembled the fan. There is a diode in the circuit, and the new solar panel is connected to it in the same way as the last one. Assuming the diode isn't blown somehow, it should also be fine.

Rachael,

Based upon what you have described, I suspect that you may have adequate voltage but insufficient amperage out of the panel (or, the diode may be blown if you might have put your battery in backwards for awhile). The first panel I tried had plenty of voltage but did not produce the level of power needed to both drive the fan motor and recharge the battery. The replacement panel has much more power output and has worked well thus far for us.

FWIW...

Re: Nicro Day-Night 2000 solar vent repair

Well, another month has passed and our repaired Vent keeps going and going, day and night, fair weather and foul, so I guess one could pronounce our repair pretty good at this point.

Re: Nicro Day-Night 2000 solar vent repair

I am grateful for this thread. It gave me the idea to refurbish my pair.

I've got my mine (brand unknown) all pulled apart, awaiting the opportunity o go the the electronics surplus to get some parts. I'd like to install batteries, but I am not sure what the voltage should be. I put the solar panel under a 60 watt bulb and got negligible voltage, I presume it actually wants to be in the sun. Frustratingly, both fanblades are the same. I'm gonna wire one motor backward.
