how will i know when a brand new solar battery is fully charged using a solar panel? will charge controller shut off after battery is fully charged?

Yes, that is one of the functions of the charge controller. I have several years experience using solar power and am happy to help out.

Depends on the controller. Some have a series of colored LEDs indicating the charging rate, some have an LCD voltmeter showing the current state of charge. Almost all, including the least expensive, drop down to a trickle charge state as the battery approaches a full charge. A battery will lose some power just being stored. The solar charge controllers will keep it charged up automatically. As ever, it is best to fully research the capabilities and limitations of each mfr. Amazon user reviews have been very helpful for me. Hope this helps.

Are there a difference with China battery and American? Jazzy says that travel distance is 15 mi but I only get 3-5 mi. I have no other transportation to get to the V.A and get food and medications. Can anyone help me get more distance?

Chico, let me add more info.Most solar charge controllers also have fuses, but some of the units are sealed making it difficult to replace the fuses leading people to believe the unit is broken. Check reviews on supplier willingness to replace units.Another important feature you want to have is a blocking diode which prevents current flow from battery back to solar panels at night. Again most mfr's provide these but check the specs carefully.

No..... and maybe.... The point of using the controller is that with small loads less than the rated amperage, when the battery is fully charged, your load is being supplied with power from the solar (bypassing the battery). This allows the charge controller to float charge the battery and also power your device.... If you are drawing lots of power through an inverter, then yes, you will need to connect directly to the battery.... Just FYI - the unit I got had an UN-replaceable fuse.... I had to create a work around to solve the problem....

As the electrical engineer answered, his keeps three batteries charged. he also mentioned he doesn't use a controller. Since this panel is very efficient it might be best not to leave it charging a single battery long term without a controller. If you weigh the cost of controller($15?) against battery, what would be your choice? This solar panel seems like it will last a long time so you might consider the controller. Most are good up to 95 watts if you decide to add to your panels.

Buy a Solar charge controller 10 watts to the battery after you hook it up via the instructions that come with it. Cost for controller was eleven bucks. No chance of overcharging your battery. The thing ,35 watt panel, charges my battery in about 6hrs.

Unless one has extensive knowledge of Solar panel and the Battery and Know how Solar Electric Systems work. I Do Not Recommend Charging a Battery without a charge controller. This panel is a 24v panel and will charge a 12v battery provided a MPPT charge controller is utilized. Appropriate MPPT charge controller for this panel would a Morningstar SS-MPPT-15L, this charger can accept up to 36v from the solar array and can charge a 12 or a 24v battery automatically.

Hello, Your question is very vague in the type of solar system that you have. A Charge Controller is usually used in a system that feeds batteries. Depending on the complexity of your system determines on the type of charge controller that you typically would have. This gauge will only tell you what one batteries current state is. The battery would have to removed from the system to get an accurate reading. The gauge check is very simple in its process to determine your battery state. What is the current voltage and hold long can it hold it for 10 seconds. Without more information, that is about as good of answer I can provide at the moment. I hope that it helps Thank you, Avel Ureno BatteriesInAFlash Tech

No once the unit is fully charged from the mains it will power any apliance & recharge via solar power how ever if the unit is drained completely it will lock down & will have to have the mains adaptor connected even if for only a second to re activate it beare in mind the solar panel trickle charges the unit & cyan take 24 hours of direct sunlight to fully recharge the unit but it will replenish its self slowly during use I find about 5% of the power out put comes from the solar panel wen used in direct sunlight but don't quote me but it is a excellent product & I can't leave with out it please not as with all rechargeable batterys the battery capacity will demimish with time if the unit is allowed to be fully drain to point of auto shut down but if left in sunlight it will recharge itself I sue mine when traveling at night & let it charge during the day hope this helps

With no load connect, it doesn't prevent the battery from over-discharge from a load. The solar panel can leach power back from the battery during the night though, and that is the discharge referred to that the controller prevents.

battery is connected the solar power also connected to normal position for charge , but at least 1 week some time 5 day the control is hang even touch any key display not change , but after disconnect battery and connect again display active it's stating to working normal.When automatic shutdown we need to restart ? or start up automatically ?

That is only part of the reason to use a solar power controller. It also controls the charging voltage corresponding to the state of charge in the battery, just like a smart battery charger.

Haven't Opened mine up so I can't help you. You might be on to something as it seems to Over Charge my Battery during the warmer months. My Solar Panel Controller does not seem to be able to account for this properly so I am forced to disconnect the Solar Panel for awhile when this happens. I plan to open mine up & look once it warms up again & the snow is gone for the season.

If there is a charge controller it should all work out of the box. I bought just the solar panel and the controller sold separately. The controller ensures the battery doesn't over charge and blocking diodes make sure the battery doesn't bleed charge at night time. I hope it all works out for you...

The instructions doesn't give enough explanation. I called the company for my inverter and asked if solar is compatible with their inverter hooked up to the charge controller. They said to keep the inverter connected to the battery. The only thing I can think of is using a 12 volt light or a small apliance could be connected directly to it instead of using the battery power. If a 12 volt light is connected directly you are taking advantage of the solar imediatly. If the same light was connected to the battery instead, the charge controller doesn't let the solar charge the battery until it drops to a certain voltage. So solar panel isn't being used to its full advantage. The instructions doesn't give enough explanation.

You might want to contact the seller Solar-X for a full answer to your question. Can only say I have had this solar panel attached with alligator clips to my 12V marine battery without the controller for a year and a half (boat is in marina in-water over winter January through March and not used for those 3 months) (live on the coast of S.C.). I have a power cut off switch and in April turned it on and the console gauge showed full charge and started the O/B upon ignition. Before purchasing this solar panel I bought a portable battery charger (just in case) and to this day have not had to use it. I credit the solar panel(sans the controller) for that. Hope this helps.

The specs are under highly controlled conditions rather than real world conditions. However, on a sunny day, with the panel aimed at the sun, and with a MPP controller, you should get something close to the rated power (maybe 80 percent of rated power or something like that). What might be happening to you is that your battery may be fully charged or nearly so. So the charge controller is limiting the current to 0.25A to avoid over-charging the battery. You could disconnect the panel from the charge controller (so the panel is not connected to anything) and check the short-circuit current and open-circuit Voltage. If those are ballpark OK, no real cause for concern. The specs are under highly controlled conditions rather than real world conditions.

Yes, this is intended to remain connected to a battery 24/7 (whether in a car or out of a car) and it begins charging the battery when solar power is available and the battery voltage is 13V or less, then once the battery voltage is raised to 14V (showing it is charged) it will stop the charging. If you will be connecting a solar panel thru a lighter plug in a car (which seems to be the easiest place), I hope the lighter remains "on" without the keys in the ignition (otherwise your "charge" power will not be getting thru to the battery making putting all of this together pointless). If you were to start a car with the panels connected up, the panels may send their rated power to help start the car (during good daylight), but they won't put out any "extra" power (they are not a battery that "store up" power or such, they just give you what they can). Once the car is started, the car alternator should instantly recharge the batteries and the green light on this should instantly come on (showing that solar power is blocked).
