LD — low-voltage LFP batteries, 5.1–32.1 kWh
Country: China · Model: LD
The LD series covers low-voltage LiFePO4 batteries from 5.1 to 32.1 kWh in a single housing. They are installed in private houses together with low-voltage hybrid inverters, and parallel connection of up to 16 modules brings the bank to 256 kWh.

Description
The cells are assembled using CTP technology, that is, the cells are placed straight into the housing without intermediate modules, which raises energy density. The smallest LD5, LD51 and LD51C have 5.1 kWh each, and the LD117 gives 11.7 kWh and a current of up to 230 A. The LD143 and LD160 hold 14.3 and 16 kWh, the LD14 and LD16 models have 14 and 16 kWh, and the largest LD32 stores 32.1 kWh. The LD117 life exceeds 6000 cycles, and the LD160 is stated at more than 8000. The housing has an LCD display, and remote diagnostics lets service staff look for a fault without a site visit. As an option the battery is supplied with an aerosol fire-suppression system, which is appropriate for installation in living spaces. Most models have IP40 and are placed indoors; the LD14 with IP65 can be mounted in a garage or under a canopy.
How to choose
The model is chosen by the required energy and by the current the inverter demands. For backup of a small house the 5.1 kWh LD5 is enough; for large banks the LD160 is better, because 16 units give 256 kWh at a life of more than 8000 cycles. If the inverter is high-voltage, the LD series does not fit, and then stackable HS units of 5.1–92 kWh are taken. Among low-voltage batteries, a close alternative is the T-BAT-SYS-LV, where the LV D150 module has IP65 protection.

FAQ
How many LD batteries can be connected in parallel?
Up to 16 units. For the LD117 this is up to 187.2 kWh, and for the LD160 up to 256 kWh.
What is the cycle life of LD series batteries?
The LD117 is rated for more than 6000 cycles, and the LD160 for over 8000 cycles.
Do LD batteries have a fire-suppression system?
Aerosol fire suppression is available as an option. It is ordered when the battery is placed in a living space or next to one.
What is the maximum capacity of a single LD battery?
The largest model, the LD32, has 32.1 kWh, and the smallest, the LD5, LD51 and LD51C, have 5.1 kWh each.
Which LD battery can be installed in an unheated garage?
The LD14 has IP65 protection and is placed in a garage or under a canopy. The other models with IP40 are designed for dry rooms.
