Pika Energy’s manufacturing headquarters in Westbrook, Maine, is also the site of a DC nanogrid using solar power, batteries and DC lighting connected by Pika inverters, optimizers and charge controllers. Here’s a photo of the solar-powered backup system, which directly powers the DC lights with exceptional efficiency.
Note that this system includes two battery banks and two sets of inverters, for testing purposes. A true Pika Energy Island requires only one blue box (The Pika Islanding Inverter X7601, at center), and a high voltage battery. For our demo setup, when that red AC breaker switch is thrown, the grid goes away and Pika’s system keeps the lights powered using solar, batteries, and the Pika Islanding Inverter X7601.
Equipment used in the microgrid includes:
Qty 9 LG 315 solar modules
Pika Islanding Inverter / X7601
Qty 2 Pika Battery Charge Controllers / B801
Pika Grid-Tie Hybrid Inverter / X3001
Qty 1 Pika PV Link Optimizer / S2501
Qty 6 Aquion Energy S-Line Battery Stacks
Qty 8 Trojan 6V L16RE Deep Cycle Batteries
Outback Power Systems DC Breaker Panel
MidNite Solar DC Combiner Box
DC lighting arrays
Here’s a one-line diagram of the system shown above.
