“…The current, voltage, power, and energy are the main data to be monitored, but due to the technology development, the batteries and the PV panels lifetime can also be monitored as per issues = in Good Condition; ation and identify the degradation of the individual PV panel. The DC optimizer [43] provides the same benefit as the micro-inverter for the battery monitoring, but the DC optimizer does not increase the single point of the failure condition. Table 5 shows the comparison of the string inverters, micro-inverters, and DC optimizers with different companies.…”

“…Additionally, the micro-inverter has a unique serial number which makes it easy to monitor each PV panel's power generation and identify the degradation of the individual PV panel. The DC optimizer [43] provides the same benefit as the micro-inverter for the battery monitoring, but the DC optimizer does not increase the single point of the failure condition. Table 5 shows the comparison of the string inverters, micro-inverters, and DC optimizers with different companies.…”

This paper is the companion paper of Remote Microgrids for Energy Access in Indonesia “Part I: scaling and sustainability challenges and a technology outlook”. This part II investigates the issues of photovoltaic (PV) systems with respect to the planning, design, and operation, and maintenance phases in microgrids in Indonesia. The technology outlooks are also included as PV has an important role in providing electricity in the underdeveloped, isolated, and border areas. The data in this paper are from PV microgrids located in Maluku and North Maluku, which are two provinces where there is barely any grid connection available and thus very dependent on remote microgrids. The data are obtained from interviews with Perusahaan Listrik Negara (PLN) and NZMATES, which are an Indonesian utility company and a program for supporting role for the PV systems in Maluku funded by New Zealand respectively. Common issues with respect to reliability and sustainability are identified based on the provided data. Advanced technologies to increase reliability and sustainability are also presented in this paper as a technology outlook. Among these solutions are online monitoring systems, PV and battery lifetime estimation, load forecasting strategies, and PV inverters technology.
