INTRODUCTION
Thank you for purchasing a Vanner Bravo Power Inverter/Battery Charger. We are confident that you will be very
pleased with its performance. Vanner Inverter/Battery Chargers are designed and manufactured by skilled
professionals using the highest standards in workmanship. With minimum maintenance and care, you can be assured
of many years of trouble-free service.
GENERAL DESCRIPTION
There are four basic models available. The hardwired units (models with H suffix on the P/N) have 3 wires (black for
hot, white for neutral, green for GND) used to connect the AC input of the inverter/charger to the AC input power with
wire nuts, and 3 similar wires with wire nuts to connect the AC output of the inverter/charger to its AC load center.
Models with G suffix on the P/N have an AC line cord installed at the factory for connecting to AC input power and a
receptacle with a GFCI (Ground Fault Circuit Interrupter) for plugging AC loads directly into the inverter. This model
requires no wiring by the customer on the AC side of the inverter.
Bravo is a high performance combination inverter and battery charger. The inverter is connected to a battery through
proper fusing and can also be connected to AC input power. Loads connected to Bravo will be powered from the
battery when AC input power is not available. When AC input power is restored (after a brief delay to ensure that full
power is available), the load is switched back to AC input power and the battery charger activates automatically to
recharge the battery.
Inverter:
The Bravo QBC10 converts the power of a battery to 1050 watts of 120 VAC modified sine wave power to operate
lights, tools and appliances. Bravo is simply connected to the positive and negative posts of a battery system with
appropriate fusing and, when turned on, produces 120 VAC power. The inverter also has an energy saving feature
called Load Demand. While in Load Demand mode, the inverter output is pulsed. This significantly reduces the
current draw from the battery until a demand is made on its output. Continuous output of 120 VAC resumes when a
load greater than 5 watts is applied.
Battery Charger:
The Bravo battery charger is superior to standard chargers. Bravo incorporates a unique three stage charger design
which allows it to correctly charge batteries automatically. While in the BULK stage, Bravo charges continuously at full
output of 55 (27.5) amps* until the battery cells have charged to 14.2/14.1 (28.4/28.2) VDC (flooded/gel). Then the
charger goes into ABSORPTION stage, maintaining 14.2/14.1 (28.4/ 28.2) VDC until the battery is fully charged. Bravo
then automatically switches to the FLOAT stage. The FLOAT stage maintains the battery at a correct voltage of
13.2/13.6 (26.4/27.2) VDC. The three stage design keeps batteries in top condition and reduces battery failure.
*A front panel mounted Battery Charger High/Low dipswitch is provided to limit the output from 55 (27.5)
amps to 27.5 (13.7) amps
