Understanding Batteries

Trojan T105RE Battery

Understanding batteries and how we can use them in an off-grid or stand alone photovoltaic storage system is important for ensuring a long service life. Batteries convert chemical energy into electrical energy and vice versa, so deciding on what battery to use, or how many batteries you will need, depends on the power and capacity requirements of your solar energy application as well as what kind of deep-discharge and recharge cycling rate the batteries will be subjected to.

DIY Solar Power System

diy solar power

DIY solar power systems do not have to be large home built constructions as there are plently of plug ‘n’ play home solar kits available for all sorts of applications. Designing your diy solar power kit or system requires you to make a few decisions first, such as, do I want a grid-connected or an off-grid connected system, do I want or need storage batteries as part of my system, and what are my energy requirements or daily consumption. Making solar generation from a diy kit a reality helps reduce the amount of electricity you pull from the utility grid

Connecting Batteries Together

deep cycle battery

Batteries connected together in a variety of combinations can increase both storage capacity and power output compared to a single battery. When two or more batteries are connected together the resulting battery pack will have either a different voltage or a different amperage depending upon the confguration. In series connected batteries, the individual battery voltages add together to determine the battery pack voltage, while parallel connected batteries produce a battery pack capacity which is the sum of the capacities of the individual batteries

Charge Controllers

Charge controllers ensure a longer battery lifespan by preventing the connected batteries from over or under charging. Solar battery charge controllers are connected between the energy source, either photovoltaic solar panels, wind turbines, or even hydro generators and a battery bank. Connecting these renewable energy devices directly to a battery or array of batteries could result in them not being able to recharge the batteries to their full capacity or the batteries will be continually cycled between partially charged and a discharged state which will eventually destroy a lead-acid battery. Charge controllers provide a constant charging voltage preventing these battery failures

Deep Cycle Batteries

Deep cycle batteries are a must for any off-grid stand-alone renewable energy system if the lights are to be kept on during the night. Lead-acid batteries have been used in many different applications and uses ever since they were invented. Batteries store and convert chemical energy into electrical energy by means of an electrochemical reaction and the amount of electrical energy that a battery can supply is expressed in Ampere-hour units. Deep cycle batteries are used in renewable energy applications as the battery cells are charged and discharged regularly throughout the day. They may not provide instant power but their depth of charge, Amp-hour ratings and lifespan is greater

Deep Cycle Batteries

deep cycle battery

Deep cycle batteries are used to store the electrical energy generated by solar photovoltaic panels, wind energy generators and other renewable energy generating systems. As well as solar power systems, flooded cell deep cycle batteries are used in recreation vehicles for powering camper vans, RV’s or boats, to powering vehicles, carts and fork trucks. As their name suggests, deep cycle batteries are designed to deliver an amount of charge expressed in Ampere-hours (Ah) for long periods of time to a specified depth of discharge.
