We manufacture LiFePO4 battery packs that comes with 2500 + cycles life compared to Lead Acid batteries with 200 - 300 cycles life. Our Li ion battery packs come with multiples of 1kW storage. 100% discharge is allowed to utilize maximum energy stored in the batteries during night time. Li ion batteries take less time to re-charge unlike lead acid batteries and gives you long life compared to other batteries. No maintenance is required for these Li ion batteries and no replacements for 10 + years or more. We also make Li-Ion / Li-Polymer power packs for mobile / Tablet / Laptop applications. Li-Ion/Li-Polymer power packs are low cost compared to LiFePO4. But life is shorter. Li - Ion: 500 life cycles                                                   Li - Polymer: 1200 life cycles                               LiFePO4: 2000+ life cycles                              LiFePO4(hi-end): 4000+ life cycles

ERS captures reactive energy that is wasted by all your appliances and stores the energy in the battery back up, which can be used to light up your lighting system. Essentially, ERS uses reactive energy produced by your appliances to charge the batteries, then inverts the DC stored in those batteries into usable AC power and supplies it to your load.
