NOMO uses new-generation Lithium LiFeP04 batteries which offers 3 times more storage and power capacity versus conventional Lead Acid batteries. Our battery design uniquely features many small lithium iron battery s packed into a dual battery assembly that minimises stress and heat during both discharging and charging cycles ensuring long term reliability. Lithium Iron batteries are also able to discharge to an incredible 90% without any damage to them before the under voltage battery protection cuts out any further operation. Built tough to withstand the harshest and most extreme environments NOMO developed tech s lithium battery s and smart protection features are up for the challenge; Our lithium battery s are able to work in extreme heat of up to 65 degree celsius & some products can even have an optional thermal heating module added to keep the lights operating in sub freezing conditions as low as -40 degrees. Additionally, Our newly designed battery packs offer multi-protection technology that allows the individual battery s to work normally even in the unlikely event that some battery s become damaged.

Nomo use MPPT Controller ( MAXIMUM power point tracking ) protect over discharge and increase battery charge. NOMO entire range offers a break-through and valuable function in remotely operating and monitoring the performance of each system; It uses a range of wireless connection technology s such as zigbee tech to securely log-on to each solar light. Additionally, NOMO has incorporated the latest in ON LINE OPERATION PLATFORM to provide our systems with linkable communication between each solar light system that can be accessed remotely via ZIGBEE technology.
