However, Microtek specifies that a firmware update may be required for lead-acid battery operation.

Battery charging voltage, charging current and protective settings must be appropriate for the selected batteries.

Customers should obtain confirmation from Microtek or an authorized service professional before connecting lead-acid batteries.

Actual backup duration depends on load, battery capacity, battery condition, discharge characteristics, temperature and UPS efficiency.

Four batteries provide the required nominal voltage; the backup duration must still be evaluated separately.

Powerful 60 Amp Inbuilt Battery Charger

The Microtek 3KVA/48V MAX LiFe Online UPS features a powerful 60 Amp inbuilt battery charger.

These settings can be configured through the supported LCD interface.

This flexibility allows the charging current to be matched to an approved external battery system.

The maximum 60A charging current should only be selected when the battery manufacturer permits it.

Higher charging current is not automatically suitable for every lithium-ion or lead-acid battery pack.

Correct charging configuration helps maintain battery readiness while reducing the risk of operating outside approved battery limits.

Adjustable Charging Voltage and Battery Protection

The Microtek MAX LiFe 3KVA UPS supports configurable battery charging voltage.

The manufacturer specifies a nominal float charging setting of 52V DC, configurable up to 58V DC through the LCD.

It also lists overcharge protection at 60V DC.

These parameters must be selected according to the installed battery’s chemistry, operating voltage range and manufacturer instructions.

For lithium-ion applications, the battery BMS must remain compatible with the charging behaviour of the UPS.

For lead-acid applications, the required firmware and charging adjustments must be completed before operation.

Installation by a qualified professional is recommended.
