does this charge batterywhen not in use and turn on automatically when house power fails?

The PW3500-12 does not have a built-in battery charger, nor does have an automatic sensor to detect a power failure to switch to the inverter's AC power. The inverter is designed to have the appliances plugged into any of the four AC outlets on the face of the inverter. You will need to manually turn on the inverter when needed.

There is no battery associated with this device. Generally you need to buy a deep cycle battery separately to run this power inverter from. No it will not turn on automatically when the power fails. You have to manually turn on the device. If you are constantly charging your battery you could leave it on at all times, but having the battery as a go between is incredibly important to make sure the inverter receives constant current.

It sure will. When power is restored back to the unit after losing battery power it will let you know that power has been reestablished. Thanks for asking!

No I have to switch it on manually. But the great thing it charge the battery very fast.

No...when you have a power failure, it opens the circuit...just like if you turned off the light switch controlling the light/fan. Just turn the light back on using the litex remote.

It will automatically come on if it's in a powered down state and u plug it in to charge. You just have to power it back down. It does charge in a sleep state as well. I haven't really payed attention to how long a full charge takes because I charge it at night, but I can tell u the battery last up to 6 hrs. I'll look into that the next time I fully discharge the battery

Yes. It automatically turns on once plugged in, but can be shut off while charging.

Yes. At least one of the four battery level lights should come on, depending on how much charge is left.

no it shuts off automatically once the battery is chargedI use this on my wholehouse diesel generator

NO, however, as stated in the manual; In the "Automatic Charging Mode" When an automatic charge is performed, the charger switches to the maintenance mode automatically after the battery is charged. Hope this helps you.

Yes...only if it is not completely dead. What I mean, is that batteries don't last for ever, so if your battery is on its last leg, you won't be able to make it like new again. If, however, you accidentally leave the lights on or something with a newer battery, this will charge it back up. I hope that makes sense.

Absolutely, and it was tested as we recently had a several hour power loss and it had the correct time when the power came back on. 3 AAA batteries power it. It's a great unit.

Absolutely! It is constantly kept charged by your system and then provides back-up power when there is an electrical failure (by the electric company).

If you mean that you want to plug a device with a battery into it at an arbitrary time (i.e., a different time each day) and have it automatically shut off after 45 minutes, then no, it won't do that.However, if you mean that you want to plug something into it at night, for example, and let the unit charge it for exactly 45 minutes overnight, then yes -- you could program it to do something like turn on at midnight and then turn off again at 12:45.

No. It has to be manually turned on and off. It will probably run out of power and cut itself off and come back on if it were charged back up.

Power failure is not problem, unit will work when power restored without re-programimg

i recall that batteries were charged, but did not pay too much attention - it was not important as power was on and i did not expect outage any time soon :)My APC is always attached

Yes. I have it as a back battery supply for my alarm system. it only gets activated during a power outage (which is pretty infrequent). But it faithfully recharges as soon as the power comes back on. This one looks identical to the one I had previously used....and that one lasted seven years. Hope that helps.
