 Whether you're look for a battery pack for your home, business or electric vehicle, this new battery technology is what you want. With a much lower depth of discharge and a longer life span (approximately 15 years), this is the smart choice in batteries. Freedom Won Lite Home The Freedom Lite Home range covers the varying needs of homeowners and even small business premises with models ranging from the Freedom Lite Home 5/4 to the largest 30/21. These models are wall mounted offering the ultimate in space saving. The product offering increases in size through the business, commercial and industrial ranges. All models are integrated with the necessary Battery Management System (BMS) and control circuitry to protect the pack and interface with the separately supplied external inverter/charger unit – lithium cells cannot be operated without a BMS. The standard home enclosure is powder coated with white sides and face to address safety and aesthetic concerns. Energy Storage FactsLithium Iron Phosphate (Lite Home) batteries have several advantages over conventional lead-acid batteries:High energy density: more energy with less weight High charge currents (shortens the charge period) High discharge currents (enabling, for example, electrical cooking on a small battery bank) Long battery life (up to six times the battery life of a conventional battery) High efficiency between charging and discharging (very little energy loss due to heat development) Higher continuous power available RUGGED A lead-acid battery can fail prematurely due to sulphation if it is left partially charged, fully discharged, or rarely fully charged for long periods of time. A Lithium Iron Phosphate battery does not need to be fully charged, has a wide operating temperature range and excellent cycling performance. They are, therefore, the battery for very demanding applications. EFFICIENT The typical energy efficiency (energy that can be taken out of the battery compared to the energy required to re-charge) for lead-acid batteries is ~ 70%. For a LifePO4 battery, it is ~ 92%. The final 20% charge for a lead-acid battery is particularly inefficient with efficiencies of ~ 50% and can take a very long time for the battery to be completely charged. In contrast, a LifePO4 battery can achieve 98% efficiency and so can be fully charged more quickly and energy efficiently. SIZE & WEIGHT LifePO4 batteries save up to 70% in space and 70% in weight compared to lead-acid alternatives. COST EFFICIENT Lithium Iron Phosphate batteries are not more expensive than lead-acid options. The purchase price may be 10-50% more initially but this is compensated by longer life, size or weight considerations, superior reliability & efficiency. For example, a 100kWh Freedom Lite costs only 20% more than an equivalent properly sized lead-acid battery. BATTERY MANAGEMENT SYSTEM t is vital that the correct battery management system (BMS) is used to control the battery charging, in order to actively balance the individual cells that make up the battery and prevent under or overvoltage, which can otherwise destroy the battery. Freedom Won utilizes the world’s leading BMS offering superior safety, reliability and performance.

ExSolar has been busy! Load shedding came like a unwanted visitor and surprised us all. While we had a tough time keeping up with the huge influx of solar enquiries, we got some more awesome sites finished and commissioned. Thank you to all our customers for being so patient with us during that busy time. We know load shedding is bound to strike again, so be prepared before the demand skyrockets again, get a quote today and let's work with you to get load shedding ready!  If you use VictronConnect, we have noticed some people assume you need an internet connection to update compatible products. To reassure those that have asked about this – it is not the case and here is why. All firmware files are already bundled with the app, so as long as you have the latest version of the app – you have the latest firmware. In other words, let’s assume you have not visited an installation for some time and that location does not have internet access on-site. As long as you ensure you have the latest version of the app whilst still in range of an internet connection, you can then go to site and if a product needs updating VictronConnect will tell you that. This applies to Wired and Bluetooth products (be they Smart tech built in or if using the VE.Direct Bluetooth Smart dongle).
 Note: if for some unlikely reason you have any issues updating your firmware using VictronConnect, it can usually be resolved by following the steps in the firmware update and troubleshooting section of the VictronConnect manual, or by contacting your distributor.
