Charging current for batteries and battery capacity

The unit reads the connected system load and charges the batteries with available residual current from the power supply. The device performs qualified* battery tests and notifies when batteries need to be replaced. The batteries are charged gently to extend their life and protection is available against overcharging.

12 V / 24 V	Maximum charging current for batteries
NOVA FLX S	4 A
NOVA FLX M	6 A
NOVA FLX L	6 A

The battery backup has controlled charging ** (controlled charging) which prevents batteries from being overcharged and extends their service life significantly. The NOVA series must be used with AGM batteries.

Note

NOVA 12V 10A FLX S, NOVA 12V 10A FLX M and NOVA 12V 10A FLX L meet the requirements according to EN50131-6 and SSF 1014 but have not been certified.

_{* Battery test is done with power resistor and the unit is tested and certified together with UPLUS 10+ Design life AGM batteries according to SSF1014. It is these batteries that must be used to maintain the certificate.}

_{** Controlled charging means that when the batteries are fully charged, they will be disconnected electronically for standby mode for up to 20 days or when the batteries have reached 26.7 V (24 V). By discharging the batteries and charging them continuously (instead of never using them), the system extends the battery life by up to 50%. The batteries connect automatically in less than 50 microseconds.}
