n Dec 2016, building on innovations pioneered in solar technology, Growatt launches a new battery charger controller SP1000-S/2000-S/3000-S successfully. It is designed to provide an easy, reliable and cost-effective energy storage solution for the clients. SP1000-S/2000-S/3000-S integrates the inherent features of the previous generation, and it has innovative characteristics as follows:
Local graphic LCD @ four buttons, easy to operate
1. Larger color screen display and four buttons, easy to operate. Such as FDT and AC charging configuration etc.
Two MPPT built-in, compatible with dual MPPT inverter
1. Two MPPT built-in to cover different application scenarios(single MPPT inverter or dual MPPT inverter).
2. Each MPPT channel is able to work independently and adjust its output power according to corresponding situation. For instance, if An MPPT channel output power was derated, the B MPPT will add its output to compensate.
Flexible to charge battery by using off peak electricity from power grid
1. Flexible to charge battery by using off peak electricity from power grid. You can choose to charge the battery when the electricity tariff is low and discharge the battery when it is high, shortening the ROI.
2. Especially, for time period when PV solar is unavailable e.g. long rainy season, AC charging function is the key to maintain battery at good condition.
Therefore, we will bring the new innovative products to the global market. And we promise the same higher level of performance in photovoltaic applications as before. People can order the new battery charger controller SP1000-S/2000-S/3000-S since Jan,2017.
