Safety and Economical

Each battery has built in BMS for under/over voltage protection, cell balancing and temperature safe guard. LifePO4 does not explode or catch fire like lithium cobalt (found in cell phones and laptops etc…). It does not have toxic chemicals and offers four times the power density at a third of the volume compared to lead acid. For these reasons it’s safe for household use.


Yes, it is possible. It is recommended to use 40mm2 or more of wire for series and parallel connections and to ensure that the wire gauge and length are the same.

Please, attention to the precautions for series and parallel:

  1. The max connection in parallel is no more than 10 pcs. Before connecting in parallel, fully charge the solar battery and test the voltage of each battery. It is recommended to control the battery voltage difference ≤ 20mV to extend the battery life.
  2. Max series connection = 2 X 24V = 48V. For balance, before connecting in series, fully charge the battery (battery voltage difference ≤ 20mV), connect 2 solar batteries in parallel and put them to rest for more than 12 hrs, disconnect the parallel connection, and connect the batteries in series.
  3. Do not put used batteries in series and parallel with new batteries. Products from different manufacturers or the same manufacturer but different batches cannot be connected in series or parallel.
This solar battery cannot be charged with AC power, the charging voltage of the 12V 100Ah solar LiFePO4 battery is 14.2V~14.6V, and the charging current is 50A. Can use a CC/CV 50A charger to charge the battery, and it is expected to be fully charged in 3 hours.
Yes, Himax solar lifepo4 batteries are all deep-cycle batteries. Depending on the depth of DOD discharge, the number of cycle life varies. (For example, at 100% discharge, the number of cycles is about 2000, and at 50% discharge, the number of cycles is about 5000.)

AC power is prohibited from charging the solar LiFePO4 battery.

Charging the battery must be DC, and the solar LiFePO4 charging voltage requires:

  • 14.2V~14.6V for 12V LiFePO4 batteies.
  • 28.4V~29.2V for 24V LiFePO4 batteies.
  • 56.8V~58.4V for 48V LiFePO4 batteies.

Using AC to charge the battery will directly short-circuit the battery, high voltage charging electricity will directly cause the battery to overcharge, causing irreversible damage.

Inverter/charger, unless there is a description that can be used for charging 12V lithium batteries, we do not recommend that you use it to charge the battery.

It can charge for a 24V solar battery pack (not a single 12V 200Ah battery) and this solar panel charges at a current of 10.4A. This means that for a 24V 200Ah solar battery pack, it will take more time to fully charge the battery (20-21 hours for a full charge is expected).

If an additional solar panel is added in parallel, the charging current will be doubled, i.e. 20.8A, which means that charging a 24V 200Ah battery pack is shortened to 10~11 hours.

NOTE: The above charging times are limited by the sunlight. If it is cloudy or the sun is short, the battery will not be fully charged.

Unless the car charger has a clear indication that it can charge 12V 24V or 48V solar lithium batteries. If not, Himax recommends charging the battery with a special charger for lithium batteries that corresponds to the voltage to ensure the safety of the battery.

Requires 600W (2*300W) solar panels.

Effective sunshine in 1 day: 4.5H (can fully charge the 12V 200Ah LiFePO4 solar battery).

Battery series and parallel connection and load connection wire use: 6 AWG.

Maximum load power of inverter: 1000W.

Recommended inverter power: 1000-2000W.

  1. Bulk voltage:28.4V
  2. Absorption voltage:28.8V
  3. Boost voltage:28.4V
  4. Equalizing voltage:28V
  5. Float voltage:25.6V
  6. Boost return voltage:25.6V
  7. Inverter Setup: Please set up the 24V 200Ah LiFePO4 solar cell according to the above parameters.
