DELTA mini’s technical specs for solar input are: 300W, 11–75V DC, 10A max. In practical terms, you can connect multiple portable solar panels in series (i.e., connecting one panel directly to the next) as long as their combined open circuit voltage doesn’t go over 75V.
Yes, DELTA mini is compatible with portable solar panels that are 10–75V DC, 10A max and that have solar connectors. We recommend using portable solar panels that have a combined wattage of around 300W.
All rechargeable batteries lose capacity over time but how fast depends on the battery. In ideal conditions, DELTA mini’s battery will have 80% health after 800 cycles; most phone batteries and portable power stations reach 80% health after only 500 cycles.
Sure! But make sure the combined wattage of your electronics doesn’t go over 1400W unless you want to use X-Boost.
