NOTE : This system is for a larger family with quite a high energy demand, bearing in mind that with battery based solar energy systems one should take all steps to reduce excessive electrical consumption that are presented by electric storage hot water systems, swimming pool pumps, large wall ovens and heaters ; if these are part of the scenario then some of them can just be left onto mains power only. The point being that if you can address most of your critical and primary load appliances with the battery based system then it is simply a matter of time before you begin to fully understand your options regarding smarter uses of electrical appliances and reducing consumption. Invariably we find that after say a 12 month period , most customers have reduced their peak electrical load by a substantial amount just by living off of battery power and taking an interest in watt is going on with such.
All of the Planet’s Suite systems are capable of country style, fully stand alone operation, without any mains connection at all, but if you go fully stand alone, then you must increase the battery capacity to give extra days of storage. A fully stand alone system with a Nickel Iron battery would normally have 4 to 5 days of energy storage capacity. Thus ,this Mar’s system would have at least 48 KWH of storage. ( 4 x 12 KWH average daily use = 48 KWH ) This would be half the amount required if you were attempting to use a conventional Lead Acid battery, because in that case you should always stay above 50% discharge to prevent plate sulphation. With the Nickel - Iron battery, practically all of the storage capacity is useable , so it may be greatly reduced in capacity. All in all, the advantage of NiFe is not very much more expensive for a battery that can outlast the solar panels themselves.
