DC to AC SSRs are common. They can be triggered by 5V arduino outputs [https://www.ebay.com/itm/174560988912?hash=item28a4a54ef0:g:1AAAAOSwKqJgNt1X] or by higher voltages [https://www.ebay.com/itm/224375129413?_trkparms=amclksrc%3DITM%26aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D234476%26meid%3Da2c8a175f18143ea9c4e5deae5f1cc9e%26pid%3D101195%26rk%3D3%26rkt%3D12%26sd%3D265365262944%26itm%3D224375129413%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv9PairwiseWithPLXWeb%26brand%3DUnbranded&_trksid=p2047675.c101195.m1851&amdata=cksum%3A224375129413a2c8a175f18143ea9c4e5deae5f1cc9e%7Cenc%3AAQAGAAACAPFQMekzD6%252B6nnoybSfb%252BfvDsrq9OIUrH%252F7iNI8KzFuYZLbaOLfGDb8sykFkyaxRMbx4NVz5jzruAorq4WqmzeF7indeltGE2Db0u4Glge3xgTdCSB0GkV3rpL2bcwAfRI5kOu7siXOsTY7Wl9yvLAC%252BKeTB75ALS47ik7F7N18EV5zceZN4r%252FZNTN2sjqorx7ldjaT23lBCcWoRb7szij9IJ3QyeZ07DBuwd4rMG0mUgWPo%252FhHwzsxQ5ODuPySDjKztsDjmpg2JxbzNk0KgFcRx%252F1HXLwn8zcx4kcdTaBYVxxSGRSQF8tEfh33F6MNjtyh9cqX0P6dJne9Um90vhnawKJwoJPK7KI0%252Bf0AoLRike4oZE%252BrJ1kB6j2AvFMXdnDPPV0CgsKmsJP0Z544lczZSJknpYNf1xECaCybZDIeJNGFJAUqQSTkqZIiHdcABW9sdf2xdz3mm4vVtmxDSVsMVPWTsE4RdtiN%252Bw50bB1CkTCrglGKfcgbCyoPtx%252BUpdpG%252B0eaXC7IGDoIyzpARFsCs%252BBGbSY18X6REiwHpqO%252BBPdwxYP0t0cpBEJ%252Bkj1FDwsZ5PM71xeMrkOO2ARPvKXNM9wCE6gOwrAcxEjMHV0h%252Ff97q34IStuef8q8DE94XilsdqWugFfbUJElMFLSUX2W9eYFVuvfHVJSeFIQhTurj%7Campid%3APL_CLK%7Cclp%3A2047675].

About
SSRs have very long life, but they waste a lot of power when handling large loads, unlike solenoid relays which only use 0.5W or so, say 25ma x 12V. But solenoid relays have much shorter lifetimes.

DC to AC
DC to AC SSRs are common. They can be triggered by 5V arduino outputs [1] or by higher voltages [2]. They can also trigger DC loads at much lower amps - this is an artifact of zero voltage crossing with AC. Here is a video on relay switching with Arduino - [3].
DC to DC
- 220V DC, 60A rating - [4]. 4 of these and we have a 240A welder switched from a 24V DC battery pack source? Using the Universal Controller and Scalable Battery Packs - that makes for a $30 welder for 240A if the battery packs are available.
