ESS for Solar Self-Consumption
XGW Digital Technology (Shenzhen) Co., Ltd. is a China-based manufacturer of Energy Storage & Battery Solutions — telecom batteries, UPS lithium batteries, residential and commercial & industrial ESS. Pairing ESS with PV lifts self-consumption from about 30% to 60-80%.
The Problem
Solar peaks at noon; load peaks in the evening. Without storage, excess PV is exported cheaply.
The Fix
Store midday PV and discharge it during the evening peak and overnight.
Sizing
Match the battery to daily surplus and evening load, not array size alone.
Value
Lower bill, lower grid dependence, and backup during outages.
Do I need ESS if I have net metering?
With weak net metering, yes — storage captures value the export tariff misses.
Can ESS work off-grid?
Yes, with the right PCS and controls; XGW systems support islanded operation.
