SAFETY INSTRUCTIONS WARNING: This chapter contains important safety and operating instructions. Read and keep this manual for future reference. Before using the unit, read all instructions and cautionary markings on the unit, the batteries and all appropriate sections of this manual. CAUTION --To reduce risk of injury, charge only deep-cycle lead acid type rechargeable batteries.
INTRODUCTION This is a multi-function inverter/charger combining functions of inverter, solar charger and battery charger to oer uninterruptible power support with portable size. Its comprehensive LCD display offers user-configurable and easy- accessible button operation such as battery charging current, AC/solar charger priority and acceptable input voltage based on different applications.
Model Wire Size Cable(mm ) B-3000 External 1 x 5AWG battery cable Connect external battery packs as below chart. Make sure polarity at both the battery and the inverter/charge is correctly connected and conductors are tightly screwed into the battery terminals...
CAUTION!! There are two terminal blocks with "IN” and "OUT"” markings. Please do NOT mis-connect input and output connectors. Suggested cable requirement for AC wires Gauge Model B-3000 AC input 12 AWG and output cable Please follow below steps to implement AC input/output connection: 1.
3.5 PV Connection CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter and PV modules. Suggested cable requirement for solar panel Cable Size Model B-3000 Solar 14AWG panel connection cable PV Module Selection: When selecting proper PV modules, please be sure to consider below parameters: 1.
Take 250Wp PV module as an example. After considering above two parameters, the recommended module configurations are listed as below table. Solar input Qty of panels Total input power Solar Panel Spec.(Reference) - 250Wp (Min in serial: 4 pcs, max. in serial: 12 pcs)...

4.4LCD Setting After pressing and holding ENTER button for 3 seconds, the unit will enter setting mode, Press "UP" or "DOWN” button to select setting programs. And then, press "ENTER" button to confirm the selection or ESC button to exit.
4.5 Display Setting The LCD display information will be switched in turns by pressing "UP” or "DOWN” key. The selectable information is switched as below order: input voltage, input frequency, PV voltage, charging current, PV power, battery voltage, output voltage, output frequency, load percentage load in Watt, load in VA, DC discharging current, CPU Version.
Battery Equalization Description Equalization function is added into charge controller, It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalization also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this condition,called sulfation,will reduce the overall capacity of the battery,...

In Equalize stage, the controller will supply power to charge battery as much as possible until battery voltage raises to battery equalization voltage. Then, constant-voltage regulation is applied to maintain battery voltage at the battery equalization voltage. The battery will remain in the Equalize stage until setting battery equalized time is arrived.
