1. SR Series solar UPS With AVR Function
Key Features:
Brief Introduction:
SR series solar UPS is a smart multifunctional solar inverter, consisting of inverters,
automatic voltage regulator, conversion circuit, main control circuit and display alarm
circuits, etc. designed to protect your computer and other important electronic equipment
from power failure, brownouts, sags and surges. The solar UPS can filter out the small
voltage fluctuations, when meeting big voltage disturbance, solar UPS can disconnect AC
input by solar ups internal circuit, so that avoid influencing your equipment. SOLAR UPS can
offer uninterruptible power supply by lead acid battery or lithium battery until the utility power
recover normally. when the utility power is normal, SOLAR UPS has voltage regulation
function by internal automatic voltage regulator. meantime charge the battery. When the
utility power is unnormal, solar inverter can change the battery energy into pure sine wave
AC power, make the load work.
Apply to Computer center, Network management center, Communication system, Automatic control system, Precision instrument and equipment, household
appliances etc. widely apply to home inverter power supply and solar energy off grid inverter power supply (configurate solar panels and solar controller) etc.

2. LCD Display (Turn Screen can display Input parameters, output parameters, battery parameters, Power parameters, Inverter parameters etc, can see every
parameters simply by each LCD screen)
1. Online interactive mode design: high-efficiency, high-power charging.
2. Adaptive output frequency adjustment: By automatically tracking the input frequency, adjust the battery inverter's output frequency, when just Battery inverter
without utility power, can switch the output frequency via ups front panel.
3. Intelligent interactive regulator: Relay fast interactive switch, with wide input voltage range, improve the output voltage regulation accuracy.
4. Intelligent digital control technology: Adopts 32-bit high-speed microcontroller circuit control, parameter setting, operation management, advanced self-test and
self-detection feature, can self-test and fault analysis all the independent circuit on the circuit board to perform a self-test and fault analysis. Adopt SPWM
conversion technology, pure sine wave output, to meet your needs.
5. Efficient inverter technology: Adopt ultra-low internal resistance power MOSFET as a power conversion switch, make the work efficiency of the inverter higher,
make the performance more stable and reliable.
6. Perfect protection features: input voltage, frequency overrun protection, surge voltage protection, over-current protection, output short circuit protection, over
temperature protection, battery overcharge and over discharge protection.
7. Intuitive LED status indicator: the workflow type status indication at a glance.
8. Humane screen dynamic LCD display: the operational status and data visual display, multi-screen data query.
9. Output no-load protection function: when the battery inverter work, if the output load is very small, five minutes will automatically shut down-load protection.
10. High-performance dynamic characteristics: a variety of feedback control using the the instantaneous control mode and rms, both to achieve a high dynamic
adjustment, but also reduce the distortion of the output voltage.
11. Intelligent battery management: three-stage intelligent battery charging, automatic battery powered environment are charging and float conversion, temperature
compensated charging, discharge management to extend battery life and reduce the burden on the administrator.
12. Intelligent detection function: the system microprocessor from time to time for all the power state, breaker status, fuse status and all the circuit work state line
detection, if any fault protection and alarm to notify the administrator immediately.
