CHLX Series lithium-ion solar batteries are designed and tested to thrive under the sometimes rigorous conditions off-grid or hybrid inverters and battery chargers can place on deep cycle solar batteries. This battery's capacity is 3.6 kWh; a 1.8 kWh capacity version is also available.
The CHLX's lithium ferro phosphate (LiFePO4) cells are safe, maintenance-free, highly efficient, and will last an impressive 2,000 cycles cycling to a full 100% depth of discharge (or 5,000 cycles when cycling to 80% DoD).
Up to 4 of these 12V, 3.6 kWh batteries can be used in series to create systems of 12V, 24V, 36V, or 48V, or you can use up to 4 of them in parallel for a higher capacity 12V battery bank. All parallel strings must be maintained within 0.2V of each other.
Unlike other lithium solar batteries, CHLX batteries are cold-rated to work in ambient temperatures as low as -22°F / -30°C. During these sub-freezing conditions, CHLX batteries utilize charging current to activate an integrated heating film to warm their internal temperature. Once the battery warms itself to a temperature above freezing, it proceeds with normal solar charging.
