“…Thus, this poses no problem of the operation to a solar panel to put it in open circuit (without load). A wide range of solar controllers operate in PWM (Pulse Width Mode) mode [20,21] to comply with the charge states. The solar panel is brought into contact and is cut from the battery every 6.25 nanoseconds according to our regulator on the basis of the SOC of the battery (bulk, absorption or boost and floating).…”

“…The control by a rectangular signal of the PWM (Pulse Width Modulation) type through the digital pin 9 of the Arduino board varies the duty cycle which represents the ratio between the conduction time and the total switching period. During its operations, the MOSFET turns on and off until the peak power point of the PV (photovoltaic panel) is reached where a local algorithm is implemented as a test title named P&O (Perturb and Observe) [20][21][22] to power a 12 V lead acid battery. Control and monitoring units are powered by the battery which is charged by the DC/DC converter.…”

With the continuous growth of energy consumption, the rationalization of energy has become a priority. The photovoltaic energy sector remains a major occupation for researchers in the field of production optimization or storage methods. The concept developed in this work is a mixed optimization approach for energy management during battery charging with a duty cycle. A selective collaborative algorithm intervenes to choose and use the appropriate results of the few techniques to optimize the charging time of a battery and estimate its state of charge by using the minimum possible tools. This is done using a collective database that is accessible in real time. It also effectively allows the synchronization of information between several customers. This approach is performed on a mobile application on android, through a Google Firebase platform that allows us to secure collaborative access between multiple customers and use the results of the calculations of some algorithms. It gives us the values obtained by the various sensors in real time to accelerate the charging speed of the battery. The validation of this approach led us to practice a few scenarios using an Arduino board to show that this approach has a better performance.

“…The dc voltage generated by solar PV is always changing every time due to the irradiation and ambient temperature impacts that affect the power produced. In order for the efficiency of power generated by solar PV match with the load impedance in all weather conditions, it's required the maximum power point tracking (MPPT) performance by DC-DC converter [7]. Through MPPT the power fluctuation from solar PV can be easily stored into the battery, then through ISSN: 2302-9285  Design of constant output voltage DC-AC inverter for batteryless solar PV system (Agus Risdiyanto) 1327 the DC power the inverter is stored in the battery with a stable voltage channeled to AC loads that are used for night or daytime purposes.…”

This paper introduces a DC-AC inverter design that operates stand alone to deliver power from solar photovoltaic (PV) to the load directly without going through the battery. In batteryless solar PV, the output voltage of solar PV always varies according to solar irradiation, temperature, so that it becomes a challenge in modelling DC-AC inverter with constant output voltage. The design consists of a boost converter, h-bridge switching and driver, and LC filter to generate sinusoidal ac voltage as output to load. To ensure a constant inverter output voltage, the design equipped by a close loop PI controller based on voltage control mode. The design modelled and simulated by PSIM. PV dc input was set variation according to the irradiation value (W/m2) and the output connected to a load that has rated voltage of 220 Vac and 3.4 A of nominal current. The results show that in the irradiation variation 600-1500 W/m2, the inverter was able to maintain the output voltage of 220 Vac ± 0.91%, 50 Hz which is still in the voltage range based on standard. The efficiency produced by DC-AC inverter 97.7 % at 600 W/m2 and 83.6 % at 1500 W/m2.
