Steca Electronics for an ecological future

The Solarix PRS charge controllers are universal charge controllers, which means they can be used with lead-acid batteries or gel batteries without the need for complex configuration settings. For larger projects, the charge controllers can also be equipped with special functions. These include the night light function, and selectable charging plateau and deep discharge protection voltages.

Charger - Battery Calculation
 

 
 

One of the most frequently asked question is, “how long will the batteries last?’. This question cannot be answered without knowing the size of the battery system and the load on the inverter. Usually this question is turned around to ask “How long do you want your load to run?”, and then specific calculation can be done to determine the proper battery bank size. 

 There are a few basic formulae and estimation rules that are used 

 Formula 1 - Power in Watts (W) = Voltage in Volts (V) x Current in Amperes (A) 

 Formula 2 - For an inverter running from a 12 V battery system, the DC current required from the 12 V batteries is the AC power delivered by the inverter to the load in Watts (W) divided by 10 

For an inverter running from a 24 V battery system, the D.C. current required from the 24 V battery is equal to the A.C. power delivered by the inverter to the load in Watts (W) divided by 20. 

 Formula 3 - Energy required from the battery = DC current to be delivered (A) x time in Hours (H) 

 The first step is to estimate the total AC watts (W) of load(s) and for how long the load(s) will operate in hours (H). The AC watts are normally indicated in the electrical nameplate for each appliance or equipment. In case AC watts (W) are not indicated, formula 1 given above may be used to calculate the AC watts by multiplying 120 VAC by the AC current in Amperes . The next step is to derive the DC current in Amperes (A) from the AC watts as per formulae 2 above. An example of this calculation for 12 V inverter is given below. 

Let us say that the total AC Watts delivered by the inverter = 1000 W 

Then, using formula 2 above, the DC current to be delivered by the 12 V batteries = 1000 W ÷10 = 100 Amperes 

Next, the energy required by the load in Ampere Hours (AH) is determined. For example, if the load is to operate for 3 hours then as per Formula 3 above: 

Energy to be delivered by the 12 V batteries = 100 Amperes × 3 Hours = 300 Ampere Hours (AH). 

Now, the capacity of the batteries is determined based on the run time and the usable capacity. From Table 1 above, the usable capacity at 3 Hour discharge rate is 60%. Hence, the actual capacity of the 12 V batteries to deliver 300 AH will be equal to 300 AH ÷ 0.6 = 500 AH 

And finally, the actual desired rated capacity of the batteries is determined based on the fact that normally only 80% of the capacity will be available with respect to the rated capacity due to non availability of ideal and optimum operating and charging conditions. So the final requirements will be equal to: 

500 AH ÷0.8 = 625 AH (note that the actual energy required by the load was 300 AH) 

It will be seen from the above that the final rated capacity of the batteries is almost 2 times the energy required by the load in AH 

Thus, as a thumb rule, the AH capacity of the batteries should be twice the energy required by the load in AH. 

For the above example, the 12 V batteries may be selected as follows:

Use 6 Group 27/31, 12 V, 105 AH batteries in parallel to make up 630 AH
Use 3 Group 8D, 12 V, 225 AH batteries in parallel to make up 675 AH

 




Warranty Information

2 Year manufacturer Warranty. - 30 days CEB Return Policy.



From CEB Return Policy Extras

Most of unused products can be returned back to us for a replacement or refund within 30 days of receipt. All returned items must be in new condition with all original packaging, paperwork and accessories supplied. All returns have to be send back via a traceable method such as Fed Ex, DHL, Purolator and USPS or similar. Return freight and original shipping are non-refundable.

All special orders, electrical appliances, appliances of any nature, items returned without original packaging or packing materials, and items sent directly from the manufacturer may be subject to a restocking fee of 10-25%. Please call us before you perform your return in order for us to issue an RMA prior any shipping is undergoing.

Please include your order number along with RMA issued by one of our staff. Without an order number and an RMA number, it will be very difficult to trace the order for the returned merchandise associated with and all the process will drag for weeks or month to come. In order to complete the return procedures please fill in the forms and follow our instructions.

Return Instructions

  1. Your Return Package

    All returns must be in their ORIGINAL PACKAGING, in a resalable condition.

To obtain your RMA and any additional return info you may need, please call our friendly, ready-to-help support team toll-free at 1.800.339.9171 or email us at returns@cleanenergybrands.com.
     
  3. Ship Your Return

     Because we want your return experience to be as hassle-free as possible, we strongly recommend that you fully insure your return shipment so that you’re well protected in the event that the package is lost or damaged in transit. UPS & FedEx provide traceable shipments, complete with a proof-of-delivery feature that guarantees that your package is delivered to the intended location. We urge you to use a carrier that has both tracking and proof-of-delivery capabilities and that you retain that tracking number. Please be advised that postage charges are non-refundable, and that CleanEnergyBrands is not responsible for any packages lost or damaged during transit. This includes packages sent via USPS to an international or overseas destination.


Defective Product; Incorrect Product

Please call for an RMA so we will arrange for a return for the defective/incorrect item and replace it at no cost to you. The item must include its original packaging and be in as-new condition with the packing slip, all warranty cards, and accessories (if applicable).
