| dc.description.abstract | Portable solar power stations with compact
solar panels and lithium-ion batteries are useful for
outdoor activities like camping and hiking for clean and
renewable energy. This paper presents the development of
a backpack style portable solar power station with weight
less than 6 kg, that delivers 500 W for 30 minutes after one
charge. It uses a 100 Ah, 3.7 V, lithium-ion battery with
foldable solar panels and delivers sinusoidal 230 V, 50 Hz,
AC output through standard socket outlets. Multiple
outputs are provided to enable several devices to take
power simultaneously, for example charging multiple
devices. Solar panel output is fed to a push-pull converter
that produces constant 400 V DC voltage for an H-bridge
inverter which is operated with sinusoidal PWM to produce
sinusoidal, constant voltage, and constant frequency AC
output. The overall design is compact, sustainable, and
adaptable to various weather conditions, to provide a
green option for outdoor enthusiasts for a better outdoor
