Will this unit give me the total watt hr produced by my solar cell. Do I need to hook it to a battery to get the total watt hr?

Hi! It will give you the watt hours produced on the "source" site that flows to the "load" side. It doesn't necessarily require a battery, only be aware that it is reset to 0 Wh whenever the voltage drops below 6 volts, so you should hook it up (at least the meter) to a battery if you want to keep your Wh from the previous day stored over night. Also, it does not measure negative current, so it won't count Wh backwards, for example when you do have a battery hooked up and you draw more power through your appliances than the solar cells do produce at the time.

You Need A Charge Controller. Connect Your Battery And YourSolar Panel(S) To The Charge Controller.The Gauge(Thickness) Of The Wire Depends On The Distance From The Charge Controller To The Solar Panel And The Battery.You Should Be Able To Find Some Images online.

It only shows runtime, load capacity and voltage. For watts you should look into a kill-a-watt device like this one: http://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU I have one of those and it works great. Plug it in before the unit, then plug the unit into it and you will have the watt display of the whole ups.

The important information is how many Amps your panels are putting out and the meter tell you this. It will tell how how many amps are coming from your panels and how many amps are going to the batteries. Also tells you the amount of charge in your batteries. The more watts your panels have the more potential number of amps the can put out. The open output of a panel is about 23 volts then your controller manages this out put so as not to destroy you battery.

Without seeing the schematic for the hook up, it is hard to advise you. There should be a charge input, that would go to the solar panel. There should be a load, that should be the device you are running, and there should be a battery connection, which is of course the battery. Make sure you observe the correct polarities on all of them. They should me marked + and -. If you are not sure, use a volt-ohm-meter to check.

This device is specifically designed to be used to tie solar cells into the grid(your power system) with the minimum of issues.You plug your solar inverter into any outlet of your home and up to two of the 136 watt flexible solar cells on the DC side of the unit ...vowla you have an inexpensive very automated solar system that is easy to add wattage to. I have not had time to install mine yet. Good luck!

This unit takes 3amp @ 12 volts. This unit will not work well with solar unless you use a high out put battery.

Directly? Probably not. The output from the panel is DC. It needs a controller to settle it to c. 12+ volts (to charge battery.) If your radio works on 12v DC you are set. If it runs on 110v ac you will need an inverter (DC to ac).

Just started mine. The load goes to the equipment you are powering, the battery goes to the battery as indicated. This unit is to automatically control the charging of the batteries only when needed and take power from either the solar cell or battery when the load is on. I can give more in a couple weeks after mine has been fully tested. If you hook the batteries to the load terminal it can overcharge the batteries and cause problems, maybe even fire. Not knowing how you are using this it is the best I can answer. Correct connections will be important if the load is not constant.

If you supply enough current to do both, then yes. I run a pump and charge batteries all day and then the pump runs most if not all night. go to backwoods solar or northern arizona solar or advanced solarr in calpella ca for free worksheets for determining totals of all loads in watt hours versus solar panel(s) output. there are other factors as well, length of 12v wire run, and lighting wire run as well. but simply, solar panel output x hours of actual panel output minus loss of conversion minus loss of wire runs gives you watt hours of power available for lighting or charging or both. the unit will do it no problem. a little tricky to set up......... see other answers If you supply enough current to do both, then yes.

Yes it does gives you the Amp Hour & Watt Hour (1000 Watt Hour = 1 unit of electricity) reading to monitor your system and especially battery capacity. Accumulated values of [Ah] & [Wh] resets when voltage goes below 4v or shut off.

This unit it a grid tie inverter you hook your solar panel(s) directly to it and plug it into your homes electrical outlet. It can produce up to 300 watts of power into your homes electrical system

It will monitor total wattage. But you will know how much each individual device consume once you turn it on.

This is a good solar panel. I have 2 batteries connected parallel, + to +, and - to -. This gives me the same voltage- 12 volts. I run my garage door opener and some accessories in my garage off a power inverter. The Ramsond solar charge regulator shuts off when batteries are full. Like T.J. said, make sure you aim the panel for best results, and hopefully its not foggy where you keep your boat!

The box says the solar panel outputs 5.0v / 70mA and the unit itself (battery pak) will output 5.0v / 500mA. Size 3.0" wide (stretched) 5.5" tall, 0.7 thick.

I installed mine recently, and measured the power, but not the current directly. In standby, the KillAWatt shows 0W, and powered it draws 4.7W. This includes a small wall wart PS, with the illuminator attached by a 100' siamese cable. These numbers are close to what gth posted, so I'd rely on his more precise numbers.

The one I bought was 30 watts, but you can get different wattages in their line. The Instapark they mention here are the brackets you buy to mount your panel. It is not a solar panel.
