This all in one charge controller board includes:
Designed, assembled and quality checked in Missouri USA using global parts.
Completely pre-wired and ready to connect to your batteries with heavy duty fine stranded copper cable, tinned copper lugs, and dual wall heat shrink.
to high customer demand, we've now added a 500 watt grid tie inverter
as a diversion load. Using solar only, when your battery reaches full
charge the charge controller activates the grid tie inverter feeding
excess power directly into your home's electrical circuits saving you
money (this can happen quite frequently during the day).
The grid tie inverter plugs into any 120 volt AC 60 hertz grid power connected wall receptacle (outlet). The optional DC to AC power inverter connects directly to your battery bank allowing you to power up 120 volt AC devices directly. In addition, the optional DC to AC Aims Power Inverter works as a 'back-up' or 'stand-alone' unit providing you with another source of free power whether the grid is working or not. Being able to run lighting, emergency equipment, and keep your refrigerator cold when the grid is down is a valuable benefit! If you do not have grid power, see our other All In One Charge Controller Boards for stand alone or remote power.
Additional important info:
made some important modifications to the assembly to make the grid tie
inverter operate and to operate safely and reliably. The grid tie
inverter alone cannot power devices directly. It must be plugged into a
wall outlet connected to grid power. The optional DC to AC power
inverter can, however.
We recommend 250 to 1000 watts total of
24 volt solar charging panels on small or medium sized battery banks
and up to 3,600 watts on larger battery banks. The charge controller
will come preset to disconnect the incoming solar power when the
batteries are full therefore if the electric grid power is OFF you will
not overcharge your batteries. This is important because the grid tie
inverter must 'see'grid power ON to feed power to it. The charge
controller will still however go into a diversion cycle lasting up to 5
minutes each time.
Because grid power is not 100% reliable, we are unable to allow the connection of wind turbines directly to this control board. However you may use an additional charge controller of suitable size and with its own diversion load to connect wind turbines to the same battery bank. This will help fill the batteries even faster and can provide valuable power at night. Even though the grid tie inverter is connected and prewired to the control board, it is not UL1741 listed. A common question we're asked is "Can I connect the grid tie inverter output to the regular battery inverter outlet/receptacle or visa versa," the answer is NO as this would most likely cause failure of the system in part or in full (i.e. irreparable damage). This controller board is simple to install, but, if in doubt, hire an electrician to help you.
Some of the key features of this controller are:
Some specifics about the points made above:
The microprocessor is the heart of the controller. It is given the battery voltage and the user changeable trip points. This information is analyzed and acted upon.
The Battery level is checked, and based on that info, the Green LED flashes or is illuminated as follows
Steady green means the battery is full.
The red LED is illuminated when the battery is being dumped at 28.8 volts (or the charge source diverted.)
The dump remains active for a minimum of 5 seconds, at which time it is checked by the microprocessor. If battery voltage drops below the "Dump Cancel " level, the dump is disabled, otherwise the dump is continued and rechecked every 5 seconds.
When you click the "TEST" push-button - the 5 second cycle is started (one time, unless the batteries are within the "Dump Start" and "Dump Cancel" zone.)
Settings are user changeable! By simply turning a simple potentiometer with a small screwdriver, you can quickly adjust the trip point.
High amp rating -- 440 Amps! -- 10,000 watts!! -- This is a MONSTER controller.
** 150 amp heat activated breakers have been installed to limit continuous current to 150 amps. Instantaneous current handling of this unit not to exceed 440 amps. **
