PWM dimming is good for constant voltage LED light bulbs, Because when PWM output high level, The voltage of PWM dimmable LED light bulbs is same as his operation voltage. It will not work with LED light bulbs that with internal driver inside (because mostly LED driver use for control the current of LED, Constant current controlling).
PWM dimmer is low voltage operation dimmer.

Lithium iron phosphate battery Cell voltage
Minimum discharge voltage = 2.0-2.8 V
Working voltage = 3.0 ~ 3.3 V
Maximum charge voltage = 3.60-3.65 V
Because of the nominal 3.2 V output, four cells can be placed in series for a nominal voltage of 12.8 V, Six cells can be placed in series for a nominal voltage of 19.2 V. Along with the good safety characteristics of LFP batteries, this makes LFP a good potential replacement for lead-acid batteries in applications such as automotive and solar applications, provided the charging systems are adapted not to damage the LFP cells through excessive charging voltages (beyond 3.6 volts DC per cell while under charge), temperature-based voltage compensation, equalisation attempts or continuous trickle charging. The LFP cells must be at least balanced initially before the pack is assembled and a protection system also needs to be implemented to ensure no cell can be discharged below a voltage of 2.5 V or severe damage will occur in most instances, due to irreversible deintercalation of LiFePO4 into FePO4.
So that the operation voltage range of led bulbs for DC dimmer PWM dimming lithium iron phosphate rechargeable batteries solar light system will be below list:
6.4V lithium iron phosphate rechargeable batteries solar lights 5.6V~7.2V
9.6V lithium iron phosphate rechargeable batteries solar lights 8.4V~10.8V
12.8V lithium iron phosphate rechargeable batteries solar lights 11.2V~14.4V
19.2V lithium iron phosphate rechargeable batteries solar lights 16.8V~21.6V
48V lithium iron phosphate rechargeable batteries solar lights 42V~54V
