They are usually very heavy due to lead acid batteries inside and not suitable tocarry easily.Another option was foldable panels fitted to fabric bases. Some of them has voltage regulators for DC output but only 2-3 different DC voltage levels... Step 1: Main Parts Required When I found Seifert Magnus Midi 63 toolcase in local Bauhaus, very delighted:) Eureka!it was perfectly matching size and specifications in my mind... Made of uv stable polypropylene and black in color. Dimensions 40.0x30.0x6.5cm and around 670 grams.Size well suited for two 10 Watts solar panels, has ribs on edges to protect switches and other equipments perfectly. Has handle and locks.If I design a case for only this purpose, it would be very similar to this :)Also we need 12V DC to 220V AC inverter. Found this 100 Watts unit on the web.Sanyo 4S lithium ion batteries with over / under voltage protecting and over temperature protecting circuits.Two 10W solar panels.7A Lead acid battery charge controllerDigital voltmeter from DealextremeAluminum composite panels to hold solar panelsDiodes to reduce li-ion battery voltage to start inverter (later you can disable them to save power)Switches, power outlets, screws etc.  http://www.instructables.com/id/All-in-One-Portable-Solar-Power-Unit-220V-12V-5V-A/   http://www.instructables.com/id/All-in-One-Portable-Solar-Power-Unit-220V-12V-5V-A/  Step 2: Preparing Parts 1 Started to remove aluminum frames around solar panels. You should be very careful to not to break tempered glass on it.Also removed big connector terminals and make them smaller.Then fix them to aluminum composite frames by Sika WT40 PU adhesive and test them how to fit inside of the box.When closed, panels perfectly protected during transportation and storage...Added two parallel set of three diodes (in series) to reduce top voltage of li-ion pack when required. As they gets hot, prepared cooling fins by aluminum U profile.These parts located on left side of the box, well protected ;)Also bend a small aluminum sheet to hold voltmeter.
