I want to leave solar connected when not using lawn tractor, but don't want to over charge battery. If there is a regulator, do you carry it and how much is it?

Answer: 
The solar battery maintainer does not require a charge controller. It is designed to prevent overcharging. This is the case for our solar panels of 10 Watts and less.

Answer: 
Thank you for your question. This battery maintainer will not work for this application as it doesn't have the right voltage or amperage for it. The panel's high voltage is intended for battery charging, not 12V constant device operation. The current is on 133 mA.

Rated 3.8 out of 5 by 17 reviewers.
Rated 2.0 out of 5.0 by Needs more output power It appears that the solar maintainer does not put out enough power to maintain a starter battery with a battery isolator and an auxiliary deep cycle battery connected to the engine's charging circuit. I have a battery isolator with an auxiliary deep cycle battery connected to my 1988 Ford F150 charging system. I have to disconnect the starter battery's negative cable and attach the solar maintainer to that battery in order to obtain voltage maintenance at around 12.76 volts. If I leave the (OEM) negative starter-battery cable connected to the starter battery and also connect the solar maintainer to that battery (and also leave the auxiliary battery connected to the battery isolator), the battery's voltage drops to 12.56 volts, and it seems it would likely continue to keep dropping. Evidently, it seems the truck's electrical system provides a steady, slow drain on the starter battery when connected like that, and the solar maintainer appears not to have enough power to overcome that slow drain. (I leave the solar panel mounted at the bottom of the passenger-side window to get maximum sunlight in the mornings with the truck (with cab-over camper) facing north. The panel's wire is threaded out the window and through a gap at the back of the hood and up to the starter battery. Leaving it like that seems to provide the least rigmarole for when I want to drive the truck; I only need to connect and disconnect cables and wires to drive the truck, and there is excellent visibility through the passenger-side window.) For diagnostic purposes I tried measuring the resistance in that battery-cable circuit with both the starter battery and the auxiliary battery disconnected. At first the digital multimeter shows infinite resistance. Then after several seconds, the meter displays readings that "flop" around in the vicinity of 3 mega-ohms. It also seems that that cable circuit acts as a large capacitor because it takes a while for the residual-voltage readings to drop down to the vicinity of 0.4 mili-volts and I have to short the battery cables together to get the voltage to drop that far. I also suspect that the auxiliary battery is not the major cause of the starter battery's slow discharge when all cables and the solar maintainer are connected because the auxiliary battery's rate of discharge is much slower than that of the starter battery. The starter battery is a brand new battery. May 5, 2016
Rated 2.0 out of 5.0 by Product is good but staff at Brenham Store need training on how to order products! Did not try item yet looks good. See store review. August 16, 2016
Rated 5.0 out of 5.0 by solar battery maintainers This product has preformed as advertised so far, haven't used it for a prolonged time yet, but have used them on three vehicles for as long as three weeks, with no problems. Only problem i had was that i had to order them on the internet, the store couldn't order them for me to be delivered to the store unless i used a credit card. I only use a pre paid credit card, so if i load the money on the card, i might as well order them from and have them delivered at home. August 16, 2016
Rated 5.0 out of 5.0 by Great inexpensive trickle charge for a spare riding mower battery I have a spare riding mower in a shed that doesn't have 110 volts so a regular battery trickle charger is out of the question. The mower gets used so little the battery usually discharges, then I have to remove it and bring it to the bench for charging. I picked up one of these solar battery maintainers and mounted it behind some plexiglass under the shed overhang in a way that rain, etc cannot get to it but it still collects ample sun light. Kind of like a vehicle windshield. The solar panel generates enough power, even if it isn't in direct sun light, to maintain a charge on the mower battery. So far I've gone as far as 3+ weeks without starting, then I disconnect the alligator clips from the battery posts and the mower starts right up. Time saved and aggravation eliminated. BTW: Home Depot had the best price for a solar charger like this and the only one I saw that produced a full 2 watts! June 24, 2016
Rated 5.0 out of 5.0 by great love it. Does what I need it to. It keeps my battery charged so I have power when and where I need it ( power outages)!!! August 24, 2013
Rated 5.0 out of 5.0 by product is as described Works as described. Be sure it is powerful enough to supply any constant drain items. December 8, 2015
Rated 5.0 out of 5.0 by Solar Battery Maintainer A quality item at a reasonable price. An easy way to shop. December 8, 2015
Rated 4.0 out of 5.0 by Solar trickle charge The Solar charger works as intended, and well at that. Results will vary from Location to Location, as well as Region to Region. The package states 2W output under "ideal" conditions, which roughly translates as in the middle of a field along the equator, but that is true for almost all solar panels. My area is hills and mountains, which block direct sun for several hours in the early part of the day and makes for an early sunset. 10 to 20 volt average sounds about right for this trickle charger panel under my common conditions.
