Store the Energy:
Real energy independence can only be achieved when energy storage is included as part of the renewable system design. The need for better energy storage has led to the development of new battery chemistries which offer increased cycle life and energy transfer efficiency which are ideal for use in the renewable energy market.
Lead Carbon Batteries
Super Long Cycle Life: With regular AGM batteries, 30% depth of discharge is typical. Lead Carbon batteries have a 50% depth of discharge, giving you more usable power in a smaller battery bank.
With limited sun hours for proper recharging of standard deep cycle batteries, the need for partial state of charge (PSOC) technology was realized.
Leading Lead Carbon Technology improves the charge acceptance ability, reduces the negative plate sulphation, and along with the deeper depth of discharge combine to make lead carbon batteries more suitable for PSOC applications. Use of the Lead Carbon battery in an application where full battery recharges aren’t always possible, like off-grid, can maximize your overall cycle life by up to 4 times versus a traditional deep cycle battery.
AGM Batteries – 2500 cycles at 30% DOD
LC-AGM Batteries – 5000 cycles at 50% DOD
Safety: Lead Carbon offers all the safety and convenience of an AGM battery with the cycling benefits of advanced energy storage.
Energy Density: A Lithium battery is approximately 1/2 the size and 1/3 the weight of an equivalent lead acid battery.
Advanced Lithium Energy Storage
Discharge Rate: The combination of a higher discharge rate and a deeper depth of discharge % (DOD) makes the Lithium battery the ideal choice for both an off-grid or grid-tie system with battery back-up.
Cycle Life is a measure of battery life expressed in terms of the number of charge and discharge cycles after which the battery becomes unusable. The Lithium battery is equipped with a sophisticated Battery Management System (BMS) that monitors and balances individual cells. The higher energy density of active material in lithium batteries provides over 4 times the cycle life of an equivalent lead acid battery.
Transfer Efficiency of energy produced from renewable energy sources to the batteries: The lithium battery has a 96% transfer efficiency compared to the lower 72 – 76% rate of the lead acid battery.
