Product Description


Renewable Energy Solar Array System for an Grid-tie w/Battery Backup Network


With this formula, you can calculate the number of Solar Panel required to be installed at your location to adequately satisfy your desired power (W) needs over specified desired days before recharge.

A 'How to Calculate Voltage Drop' formula between components is also provided.Watch product video.

 Inside also, is a Wire Sizing System Worksheet.

We provide you with this comprehensive "Array Sizing Calculator" designed specifically to suit Off-grid set-up.

Download this handy plug & play formula and start designing your very own Off-grid system.


Renewable Energy Battery Bank System for both Grid-tie (as Back-up) and Off-grid (Stand alone)  Solutions .

With this formula, you can calculate the number of batteries that will be needed as well as the configuration, to adequately supply stored energy that will satisfy your Power (W) consumption on a Daily basis. This formula also cover various losses to be accounted for, power factor, actual discharge current and much, much more. Therefore the run-of-the-mill calculations seen everywhere does not give a true reflection of what energy goes in and leaves the battery bank each time it is exposed to various loads.

We take  the challenges out by providing  you with this comprehensive "Battery Bank sizing" calculator to determine the number of batteries as well as configuration needed to supply back up power. Choose from a variety of Batteries offered to suit your needs as you plug the formulas.

Download  this handy plug & play formula and start your own Battery Bank designing.

Choose from an assortment of industry standard battery manufacturers specification to incorporate in your design.


Recommended below: (kW - kilowatts)
1.  Off-grid/stand alone - 7kW and over /day or just want to be independent by producing one's own energy
2.  Battery design) - for back up purposes
3.  Gridtie - 5kW and above/day
4.  Grid tie /w battery backup - 5kW and above/day

For consumption below 5kW/day, choice left up to consumer to decide whether grid tie or stand alone
NB: grid tie is sharing electricity consumption with the power company and a battery backup can be incorporated for loads/appliances that should be always on.
