Tindie Weblog | Programmable DC-DC Converter for Off-Grid Programs


With hobbyists always creating new devices, we frequently discover that powering them within the discipline might be tough! If you happen to’ve obtained entry to mains electrical energy — nice. But when not, it’s a must to rigorously take into account energy sources and choices. The Atverter is a programmable DC-DC buck/increase converter that’s versatile sufficient for use in a big number of tasks.

It could possibly settle for as much as 60VDC on the enter aspect, permitting a spread of photo voltaic and renewable vitality sources for use. Lead acid batteries might be a good way to retailer energy from photo voltaic arrays, however then getting an environment friendly DC-DC converter that may deal with various enter voltages — and in addition be bidirectional to cost the batteries if wanted — can have you ever spending ages going over energy provide designs, or taking a look at pages of DC-DC modules on provider web sites.

The Atverter is designed to be programmable, that means you possibly can set it up for all kinds of eventualities. That is significantly helpful in case your challenge must journey from place to put, the place the obtainable voltages won’t all the time be the identical. It may be monitored over UART or I2C, and can be DIN-rail mountable which is a pleasant characteristic! It additionally has the usual Raspberry Pi 40-pin header to make integration with Pis a breeze.

Hold a watch out within the coming months as vendor Picrogrid provides extra documentation and instance code, together with a photo voltaic MPPT battery charger, and establishing a DC microgrid with a Raspberry Pi!
