Solar charge/controllers

You won't be using any stand-alone solar charge controllers if you have a hybrid or solar string inverter, these have their own in-built MPPT inputs instead. But if you are hooking up to an inverter/charger you will need to charge the battery bank directly using one or more of these units. They come in a wide selection of current (Isc) and voltage (Voc) specifications which must be compatible with your solar arrays.

The DC output voltage produced will normally be automatically matched to the voltage of your battery bank, otherwise it's set with its parameter settings. The charging configuration may be controlled from the inverter/charger's parameter settings or from settings on the charge/controller itself. 

So with an arrangement with a single series string of ten 370w panels you will have a max Voc  around 410v producing 11 or 12 amps under optimum conditions.  The solar charge/controller has an input voltage range spec and a max input current spec, and you'd be looking for one with a voltage input range around 250-500v or so and a 13a max current.  The array max Voc must be below the controller rated max voltage under any temperature or irradiation conditions and therefore a 10-20% margin should be factored in where ambient temperatures can be very cold. Contrary to what may seem natural panels are more efficient in cooler conditions.
