LFP Lithium Battery Wake-up Function
This charge controller is equipped with an LFP (LiFePO4) lithium battery wake-up feature. If lithium batteries are used
with this controller, they must have an integrated battery manag ement system (BMS). The BMS typically provides
numerous safety features. When necessary, the BMS will shut -down the battery, electrically rem oving the b attery from
this charge controller. When PV power is available, this CIS controller will attempt to "w ake-up" the BMS when it detects
a disconnected battery by providing it with a current of approxim ately 100 mA, signalling that power is available for
charging. If the BMS wakes up successfully, the battery will provide voltage to the controller to resume normal operation
and allow charging. If w ake-up is not successful, the controller will continually att empt to w ake the battery up again in
increasingly longer intervals.
Ensure that no loads are directly connected to the battery for tw o reasons. First, this will interfere with the wake-up
function and will likely prevent the BMS from re-activating the battery. Second, if a load is directly connected t o the
battery, it is likely the reason the BMS has had to intervene in the first place to prevent critical discharge. Therefore, ensure
all loads are connected to the load output of the controller or, if their current is too high (in the case of inverters for
example), connect these to the LFP b attery only via a normally-open p ower relay or solid-state relay. The relay coil /
control side should then be p owered by the controller load output.
Note: The connection of a relay to the output of a charge controller requires a free-wheeling diode in parallel t o the load
output. Please pay attention t o the p olarity - the freewheeling diode must be con nected in reverse polarity.
This way the CIS can control the load and avoid BMS intervention. Even if the BMS must disconnect the battery, the wake-
up feature can then wake the b attery as necessary when PV power is available, wit hout human intervention.
