LTO 33.6V 30Ah Battery 1008Wh 10000 Cycles for Mini Inverter Solar Storage

Product Overview
This LTO 33.6V 30Ah battery stores 1008 watt hours of energy and is specifically designed for mini inverters and household solar storage systems. It captures excess photovoltaic energy during the day for use at night, reducing household electricity costs. LTO cells provide an outstanding cycle life of over 10000 times at 1C rate and 80 percent depth of discharge. The battery operates reliably from -30°C to +60°C for both charging and discharging without requiring any heating. An integrated BMS protects against overvoltage, undervoltage, overcurrent, and extreme temperatures.

Core Technical Specifications
Nominal voltage is 33.6V with 30Ah rated capacity and total energy of 1008Wh. Internal resistance is ≤65 milliohms. Efficiency reaches 98 percent. Self discharge is less than 5 percent per month. The battery uses 14 cells in series with 20 cells in parallel (14S20P). Dimensions are 515mm width, 540mm depth, and 85mm height. Weight is 25.5 kilograms. Housing is aluminum with IP67 protection. Cell chemistry is LTO. Communication is not specified.

Discharge Performance
Continuous discharge current is 30 amps. Pulse discharge current reaches 45 amps for less than one second. BMS discharge cut off voltage is 21V with reconnect at 23.8V. Recommended voltage disconnect is 21V. Short circuit protection activates within 300 to 800 microseconds.

Charge Parameters
Charging uses the CC CV method with charge voltage range of 38.5V to 39.2V. Recommended float voltage at 100 percent state of charge is 37.8V to 38.5V. The recommended charge current is 15 amps for optimal cycle life, while the maximum charge current is 30 amps. BMS charge cut off voltage is set to 39.8V.

Temperature Range
This LTO battery operates across an exceptionally wide temperature range. Discharge temperature range is -30°C to 60°C. Charge temperature range is also -30°C to 60°C. Storage temperature range is -30°C to 60°C. BMS high temperature cut off is set to 65°C. No heating is required even when charging at -30°C.

Cycle Life and Longevity
Rated for over 10000 cycles at 1C charge/discharge rate and 80 percent depth of discharge while retaining over 80 percent of original capacity. For a household that cycles the battery once daily, this provides more than 27 years of service. The long cycle life makes it a cost effective investment for home solar systems.

Connectors for Solar Integration
The battery comes with two MC4 connectors. The PV input MC4 accepts DC 33V to DC 150V with maximum 30A and 1000W, allowing direct connection from solar panels. The output MC4 delivers DC 21V to 39.2V with maximum 30A and 1000W, connecting to the mini inverter. This plug and play design simplifies installation and eliminates complex wiring.

IP67 Rugged Enclosure
The aluminum housing carries an IP67 protection rating, making the battery completely dust tight and waterproof up to 1 meter immersion for 30 minutes. This allows outdoor installation in gardens, on balconies, or on rooftops without additional enclosures. The aluminum construction also provides excellent heat dissipation.

Built in BMS Protection
The integrated Battery Management System provides charging overvoltage protection, discharging undervoltage protection, charging overcurrent protection, discharging overcurrent protection, high temperature protection for both charge and discharge, and low temperature protection for both charge and discharge. The BMS also balances cells to maintain capacity.

Applications
This LTO battery is specifically designed for mini inverters used in household solar systems. It stores excess solar energy during the day for night time consumption. Other applications include small off grid cabins, balcony solar storage, remote monitoring stations, RV solar systems, and backup power for low power appliances such as lights, routers, and small refrigerators.

Installation Recommendations
Mount the battery in a location protected from direct impact. The IP67 rating allows outdoor placement, but avoid covering the housing to ensure passive cooling. Connect solar panels to the PV input MC4 connector (DC 33V to 150V). Connect the output MC4 connector to the mini inverter (DC 21V to 39.2V). No additional charge controller is needed because the built in BMS manages the battery. For best cycle life, avoid consistently discharging below 21V.

User Benefits
No battery heater required even in subzero temperatures. The IP67 enclosure allows installation anywhere outdoors. MC4 connectors make wiring as simple as connecting solar panels. Over 10000 cycles eliminate frequent battery replacements. Lightweight 25.5kg design is easy to handle. Maintenance free operation saves time and money.

Comparison with Other Batteries
LiFePO4 batteries typically require heating to charge below 0°C and last 4000 cycles. Lead acid batteries lose significant capacity in cold weather and last only 500 cycles. This LTO battery charges natively at -30°C without heaters and lasts 10000 cycles, making it the best choice for cold climates and long term use.
